Mars Kumari: Grit and Grief

When the French philosopher Jacques Derrida defined the lingering Marxism of late-Capitalist society as hauntological, mashing together the words “haunting” and “ontology,” he couldn’t have imagined what the era might sound like. Bay Area beat maestra Mars Kumari captures the grit and grief of loss we all feel now, haunted as we are by what was here and is now missing.

I met Mars Kumari at Oblivion Access in Austin in the summer of 2023, where she gave me a demo CD of her record, I Thought I Lost You (Bruiser Brigade, 2023). I already had her record for deadverse, Mars Kumari Type Beat (2021), so I was stoked for the preview. She’s moved on and on since then with collaborations in the works with legends like Del the Funky Homosapien and Dose One and a new solo record for Handsmade Collective.

Roy Christopher: How’d you get into making music in the first place?

Mars Kumari: I first started learning music theory through piano lessons from age 6 onward, but didn’t start making my own music until around age 15/16 when my older brother gave me a pirated copy of Ableton. It was on version 8 at the time but 10 years later it’s still my weapon of choice. It took a lot of trial and error to learn (also YouTube tutorials). Throughout that period of time I’d absorb the music my brother listened to via these mix CDs he’d make, which is how I discovered MF DOOM, Del the Funky Homosapien, Crystal Castles, Flying Lotus, Nujabes, and Earl Sweatshirt, among so many others that ended up being core influences of mine.

I spent a year or so making beats by myself until I met my lifelong friends Keyvon and Shishan around 2015, and we all learned to produce and rap alongside one another. In 2019 and early 2020 when I was in university I performed alongside my good friends Nina Spheres and Parish as part of a dark ambient drone trio (collectively titled Nina Spheres). I learned much of what I know about sound design, layering and harmonics from that experience.

RC: More than any era of hip-hop, I hear the second wave of industrial acts (e.g, Scorn, Skinny Puppy, Justin Broadrick, Kevin Martin, the more ambient moments of Meat Beat Manifesto, Wax Trax Records output, et al.) in your work. Is that me just superimposing my own listening history, or do you find kindred sounds in there?

MK: I’ve been getting into the work of Justin Broadrick (specifically JK Flesh) since I saw him at Oblivion Access! I’m familiar with Skinny Puppy and Meat Beat Manifesto, but I need to get into their catalogs more. There are too many artists that influence me to name in one sentence, but Boards of Canada, dälek, Clams Casino, and Burial are some big ones for sure.

RC: What do you call it?

MK: My music?

RC: Yeah.

MK: I usually just say I make beats, even if that’s sort of oversimplifying it. My foundations have always been in industrial hip-hop, drone and shoegaze, but over the last 3 years that I’ve been performing for raves and nightclubs in the Bay, I’ve been listening to a lot more jungle, hard techno, dubstep, digital hardcore, things like that. I had listened to these kinds of music before but being around so much of it the last few years has had a major influence on my sound.

The context and emotions I associate with these kinds of music are consistently integral to the concepts behind my albums. For example, a lot of what I incorporated into Daybreak reminds me of some of my favorite memories of being surrounded by other trans people I love at parties and raves (places I’d be hearing the sort of music that inspired this) coupled with the comparative isolation of waking up the following morning alone in a world that hates people like us. It’s both of those feelings in equal measure behind the sound.

Given how important to the music the memories are, I guess I’d call it hauntology, but to me that feels more like a guiding philosophy and spirituality than a useful descriptor of the way it objectively sounds. There are many different sounds that the word hauntology describes; I think what unites them is more abstract.

RC: What does hauntology mean to you?

MK: Mark Fisher defined it far better than I ever could, but in the context of music I would say it refers to sounds that evoke the distance between yourself and something you remember. The core memory is important, yes, but all music evokes memory on some level. Hauntology centers that temporal distance between you and your memories along with the feelings that may summon (usually nostalgia or a nonspecific feeling of loss). To me it’s more of a guiding set of principles.

However, as a broader philosophy of ghost-like things and temporal disjunction, it strongly informs my relationship to identity (especially gender identity). My own experience of transition has been one of constant tension between past and future selves. Early on, I felt as if the future I had chosen to seal away by transitioning was still haunting me; these days what I feel is more of a sense of having the past selves live on as revenants in my body alongside who I am now. Even the phrase “who I am now” feels relatively meaningless when the present self is never without past or future iterations.

RC: How would you chart the progression of your sound over your last five records?

MK: I put together my first album Anhedonic Mirages (2020) using beats I had made across the previous 5 years which I resampled and reshaped using a lot of distortion, reverb, and grain delay. It serves twofold as an exploration of a new sound and a reflection of where I felt I existed spiritually and temporally in my transition (and by extension the way in which past and future selves behave like revenants). It’s very washed out and bathed in noise and the song structures across this project follow a sort of dream logic. The whole thing is pretty “lo-fi” so to speak; from here I’ve tried to achieve clearer and clearer mixes with each album.

Mars Kumari Type Beat (deadverse, 2021).

I released my next project Elysian Mourning (2021) the following February. This album is a bit more sparse and dreamlike; there’s less percussion than in the last album and what is there is subdued. The drones were the focus here. I used my SP-404 extensively for this one; something I like about the original model is the way that electrical noise stacks and multiplies the more you resample something.

Mars Kumari Type Beat (2021) once again re-centers the drums. Some of the oldest beats I’ve ever put out are on here; as such it’s much more varied in its sonic pallet. There are alternative versions of tracks from the previous two albums, beats I started in 2015, and lots of samples from tape reels. I originally released it for Bandcamp Friday that August, and dälek took a liking to it and offered to put that out on deadverse. I’m endlessly grateful that he took a chance on me.

I Thought I Lost You (Bruiser Brigade, 2023).

My next album I Thought I Lost You (2023) took two years to complete and release. There were often field recordings and found sound in the backgrounds of previous albums but they’re much more in focus here, serving as leitmotifs. For example, the ambient passage at the beginning of the final track is lifted from a cassette I found with a recording of someone’s funeral. The atmosphere of that room comes through even in the absence of the eulogy. Even when these kinds of recordings aren’t so closely tied to death, the nature of them is inherently ghost-like in their detachment from any identifiable source. All you have is the recorder’s voice, the room they were in, and to a subtler extent what they were feeling. All with no semblance of an idea of who this was, what they were like, or if they’re even still alive. A voice with no name or body is a ghost in my eyes.

Anyways, I Thought I Lost You is stylistically similar to Anhedonic Mirages, but much more refined, versatile, and massive. There are elements of jungle, noise, industrial hip-hop, and plunderphonics, all texturally united with a dense veil of dark ambience. I wanted to instill a sense of immersion into a new world. Conceptually, it’s grief as a dimension. This was released via Bruiser Brigade Records and mastered by Raphy.

Daybreak (Handsmade Collective, 2024).

My latest album Daybreak (2024) is my attempt at deconstructed club, fusing hard techno and drum and bass and house with industrial hip-hop and gossamer layers of ambience. I wanted to make something that felt really crystalline and pretty that would sound great on a live soundsystem. Most of the songs here were designed for live performances, and many times I’d audition my mixes by playing them at shows and seeing how it sounded and how people responded. I try to wear my influences on my sleeve less these days, but it is very much inspired by artists like Burial, Arca, and Eartheater. I used a lot more synths and software drums here than in earlier albums (which were mostly or entirely sample-based, it’s more of a 50/50 ratio here). I’m really proud of the mix on this one. This is my first record with Handsmade Collective.

In summary, my sound has always had industrial trip-hop and dark ambient at its core, but over time has incorporated elements of deconstructed club and IDM with an increasingly glossy finish. Improving my mixing from one project to the next has always been a priority, and the results of working toward that are showing more and more in the increased clarity and scale of the sound.

RC: What’s coming up next?

MK: A full-length album with Del the Funky Homosapien has been in the works for most of the year. It’s about halfway recorded, and I’m aiming to have it out sometime midway next year. It’s tricky for me to say how it will sound given that it’s still in the works, but in a way it unites the grit of I Thought I Lost You with the gloss of Daybreak. I just started work on an LP with Dose One as well. There are other LPs and EPs planned as well, including one with my friend Q3, one with Uboa and Hook Operator, a noise EP with Lucas Abela and another solo record. Besides that, hopefully I can get a pet rabbit soon.

Dead Channel Sky

Because of their mix of hellified gangster shit and progressive compositions, I once jokingly called clipping. “Deathrow Tull.” Well, it’s not a joke anymore. While their last few projects have been record-long concepts like the classic prog rock of old, Dead Channel Sky is mixtape-like, a carefully curated collection of songs in which every track is a love letter to a possible present. Like a mashup of distinct elements, the overall concept is there, but the result is brief glimpses into a world rather than an overview of it. It sounds crisp and classic at the same time. When something strikes us as retrospective and futuristic at the same time, it’s a reminder of how slipshod our present moment truly is.

In my book Dead Precedents: How Hip-Hop Defines the Future (Repeater Books, 2019), I draw what Walter Benjamin would call correspondences between early hip-hop culture and cyberpunk literature, the binary stars of the solar system at the end of the millennium. I exploit their similarities to illustrate how the cultural practices of hip-hop have informed the cultural practices of the now. Hip-hop was borne of the post-apocalyptic scene in the South Bronx in the early 1970s. Its repurposing of outmoded technology, the hand-styled hieroglyphic screennames on every colorfast surface, and the gyrating dance moves—an entire culture forged from the freshest of what was available at hand—mirrors the post-apocalyptic techno-scrounge of William Gibson’s Neuromancer, Rudy Rucker’s Software, and other early works by the contributors to Bruce Sterling’s Mirrorshades anthology (Pat Cadigan, John Shirley, Lewis Shiner, and Sterling himself, among others). Add the leather-clad mohawks of Afrika Bambaataa and the Soulsonic Force or Rammellzee’s B-boy battle armor and a blend of the two comes further into focus.

Juxtaposing high-tech, corporate command-and-control systems (the “cyber”) with the lo-fi, D.I.Y. underground (the “punk”), cyberpunk proper starts in 1982 and ends in 1999, from Blade Runner to The Matrix. There are works before and works since that embody the visions and values of cyberpunk, but these dates act as rough parameters for their assimilation into the larger social sphere, for the time it took cyberpunk to become cyberculture. In the meantime, hip-hop matured, went through its Golden Era, then melted into further forms. Over the same decades, it went from “Planet Rock” to “Bring da Ruckus” to “Hard Knock Life,” from Fab 5 Freddy to Public Enemy to Missy Elliott, from Run-DMC to N.W.A. to Notorious B.I.G. While other genres flirted with it, hip-hop was fickle and fey. Any tryst with the odd bedfellow was a one-night stand at best. Rap and rock birthed mutant offspring maligned by most, and hip-hop’s relations with electronica rarely fared any better.

Those twin suns—hip-hop and cyberpunk—both rose in the 1970s and warmed the wider world during the 1980s and 1990s. What if someone explicitly merged them into one set and sound? Afterall, both movements are the result of hacking the haunted leftovers of a war-torn culture that’s long since moved on.

On Dead Channel Sky, clipping. texture-map the twin histories of hip-hop and cyberpunk onto an alternate present where Rammellzee and Bambaataa are the superheroes of old; where Cybotron and Mantronix are the reigning legends; where Egyptian Lover and Freestyle are debated endlessly, and Ultramag and Public Enemy are the undeniable forefathers; where the lost movements of 1980s and the 1990s are still happening: rave, trip-hop, hip-house, acid house, drum & bass, big beat—the detritus of a different timeline, the survivors of armed audio warfare. That war at thirty-three and a third, its atrocities imprinted upon yet another generation, what someone once called, “the presence of the significance of things” without a hint of ambiguity.

clipping. is very story oriented. They deal in ontology and narrative as much as beats and rhymes. They’ve been approaching making music like writing science fiction since their conception. Two of their records have been nominated for Hugo Awards. William Hutson and Jonathan Snipes both compose film scores, and Daveed Diggs is an actor, writer, and producer. As clipping., they’ve collaborated with as many of their fellow experimental noise artists (e.g., Pedestrian Deposit, Michael Esposito, Jeff Parker, et al.) as they have fellow rappers (e.g., Ed Balloon, King Tee, Gangsta Boo, Benny the Butcher, et al.). Here those co-conspirators include everyone from the guitarist Nels Cline on the outro to “Dodger” (titled “Malleus”) to their labelmates Cartel Madras on “Mirrorshades, pt. 2,” rapper/actor Tia Nomore on “Scams,” and the wordy wordsmith Aesop Rock on “Welcome Home Warrior,” among others.

Diggs is known for intricate lyrics and rapid-fire rapping, and the tracks that Snipes and Hutson build in the background are no less complex. On “Knocking in the Back,” they employ Pulsar Generator, a 1990s-era sound-particle software program developed by Alberto de Campo and Curtis Roads; on “Code,” they sample narrated memories from the Afrofuturist documentary The Last Angel of History; and on “Dominator,” they repurpose the classic Dutch track “Dominator” by Human Resource. All of the above serves to give us a glimpse of an adjacent possible present, where hip-hop and cyberpunk are one culture.

Binary stars are often perceived as one object when viewed with the naked eye. Like those twin sun systems, it’ll take some special equipment and some discerning attention to pull the stars apart on this record. As Diggs barks on the fire-starting “Change the Channel”: Listen up! Everything is very important!

Reverberations of a Dead Man’s Ego

When an emcee finds a producer who fuels his verbals, he keeps him close. Atoms Fam, Hangar 18, and Def Jux alumnus, Alaska found just such a fire in steel tipped dove on last year’s The Structural Dynamics of Flow. A journeyman in the pits, dove’s credits run way below the surface of things, and his pedigree shows in his ability to keep the rig moving no matter. Once again on the black circles is the inimitable Marcus Pinn, steady adding nitrous to the mix. Over numerous releases in the last few years including two from 2023 alone, Alaska has settled into a style as mature as it is versatile. He knows the course comfortably now, so he can take the turns, open it up, and just drive.

Along for the ride on Reverberations of a Dead Man’s Ego are PremRock and Curly Castro (a.k.a. ShrapKnel), who with Zilla Rocca, make up three-fourths of the Wrecking Crew. All appear on different tracks here, not that keeping them separated blunts their impact in the least. Prem and The Prophet, Fatboi Sharif, are Alaska’s accomplices on “Murder by Numbers,” and fellow Atoms Family member Cryptic One joins Zilla and Alaska on “Disappearing Acts.” There’s also Bateria, a.k.a Jedi Son of Spock, on “Imposter” and Sleeping Dogs on “Vulture Stones,” among others. Those guys are all undeniably dope, but they’re only passengers here.

Alaska never lets you forget who’s behind the wheel as he drops lyrical references to everything from classic slashers and Wu-Tang to Violent Femmes and Hunter S. Thompson. It’s fun, but it’s serious. You can feel the aging aches of “Mild for the Night” in your lower back. You can also feel the frustration on “Hundred Dollar Bills” when Alaska raps, “Yeah, I’m a nihilist, but only ‘cause I’m tired of shit.” Word to the dead man’s ego.

I Thought I Lost You

Bay Area hauntologist and deadverse alumna Mars Kumari proudly presents her debut record with Bruiser Brigade, I Thought I Lost You, available December 1st.

When the French philosopher Jacques Derrida defined the lingering Marxism of late-Capitalist society as hauntological, mashing together the words haunting and ontology, he couldn’t have imagined what the era might sound like. Mars Kumari captures the grief and grit of loss we all feel now, haunted as we are by what was here and is now missing.

Renowned Detroit artist collective Bruiser Brigade, host of cutting-edge artists like Danny Brown and Zelooperz, is proud to announce the upcoming release of Mars Kumari’s highly anticipated LP I Thought I Lost You. A mystery-ridden and heartfelt collage of textures, voices, tones, and the sounds of the breathing of forgotten machines, this hour-plus journey evokes a mournful amalgamation of tenebrous hip-hop, displaced jungle, upended dark ambient and bereft power electronics. Sharing tracks with underground and independent anti-heroes: Fatboi Sharif (Backwoodz Studios), dälek (Deadverse), Uboa (The Flenser), Lucas Abela (Justice Yeldham, dualplover), SAINT ZAIYA, L. Coats, Liiight, Censored Dialogue, and Big Flowers, among others. It’s a sound collage and force of plunderphonics. It’s a record that feels like a misplaced sense of what it means to be material. Come lose yourself.

Digging D.E.E.P.

The Intellect U Well Journeys: Afrofuturism book discussion at the African American History Research Center in Houston, Texas last weekend was a blast and a blessing! Many thanks to Deborah “D.E.E.P.” Mouton, James Stancil, Tonya Stancil, Davin Stancil, Suzanne Simpson, Lily Brewer, everyone at the Gregory School, and everyone who came out.

Me and Deep Mouton at the African American History Research Center in Houston, Texas.

Deep Mouton’s book, Black Chameleon (Henry Holt & Co, 2023), takes hefty strides toward creating a Southern African-American mythology, its horror tempered by hilarity. Talking with her about it, Boogie Down Predictions, and our views on Afrofuturism, hip-hop culture, writing, poetry, performance, and scholarship was a privilege and a party. I hope we get to continue it sometime soon.

Boogie Down Predictions Event at Volumes Books in Chicago

On July 13th, Ytasha L. Womack and I met at Volumes Books in Wicker Park in Chicago to talk about our book Boogie Down Predictions and our other work in hip-hop and Afrofuturism.

Me and Ytasha Womack at Volumes. [photo by Shannon Keane]


It was a great discussion that covered the material in BDP and then used it as a jump-off point for other projects and concerns. Ytasha had just returned from Ghana a few days before where she toured the slave castles at Elmina and Cape Coast. Her stories, like so many other concepts we discussed, went backward to look forward. You truly missed a treat if you weren’t there.

Ytasha is the author of Afrofuturism: The World of Black Sci-Fi and Fantasy Culture and the forthcoming Black Panther: A Cultural Exploration. She also wrote the Introduction to Boogie Down Predictions. Here’s an excerpt:

This book, edited by Roy Christopher, is a moment. It is the deconstructed sample, the researched lyrical metaphors, the aha moment on the way to hip-hop enlightenment. Hip-hop permeates our world, and yet it is continually misunderstood. Hip-hop’s intersections with Afrofuturism and science fiction provide fascinating touchpoints that enable us to see our todays and tomorrows. This book can be, for the curious, a window into a hip-hop-infused Alter Destiny—a journey whose spaceship you embarked on some time ago. Are you engaging this work from the gaze of the future? Are you the data thief sailing into the past to U-turn to the now? Or are you the unborn child prepping to build the next universe? No, you’re the superhero. Enjoy the journey.

Boogie Down Predictions also features contributions from Omar Akbar, Juice Aleem, Tiffany E. Barber, Kevin Coval, Samantha Dols, Kodwo Eshun, Kembrew McLeod, Chuck Galli, Nettrice Gaskins, Jonathan Hay, Jeff Heinzl, Rasheedah Phillips, Steven Shaviro, Aram Sinnreich, André Sirois, Erik Steinskog, Dave Tompkins, Tia C.M. Tyree, Joël Vacheron, tobias c. van Veen, and K. Ceres Wright.

Here’s what other people are saying about the book:

Roy Christopher’s dedication to the future is bracing. Boogie Down Predictions is a symphony of voices, beats, and bars messing with time, unsettling histories, opening portals. — Jeff Chang, author, Can’t Stop, Won’t Stop

The study of hip-hop requires more than a procession of protagonists, events, and innovations. Boogie Down Predictions stops the clock—each essay within it a frozen moment, an opportunity to look sub-atomically at the forces that drive this culture. — Dan Charnas, author, Dilla Time: The Life and Afterlife of J Dilla

How does hip-hop fold, spindle, or mutilate time? In what ways does it treat technology as, merely, a foil? Are its notions of the future tensed…or are they tenseless? For Boogie Down Predictions, Roy Christopher’s trenchant anthology, he’s assembled a cluster of curious interlocutors. Here, in their hands, the culture has been intently examined, as though studying for microfractures in a fusion reactor. The result may not only be one of the most unique collections on hip-hop yet produced, but, even more, and of maximum value, a novel set of questions. — Harry Allen, Hip-Hop Activist & Media Assassin

Boogie Down Predictions offers new ways of listening to, looking at, and thinking about hip-hop culture. It teaches us that hip-hop bends time, blending past, present, and future in sound and sense. Roy Christopher has given us more than a book; it’s a cypher and everyone involved brought bars. — Adam Bradley, author, Book of Rhymes: The Poetics of Hip-Hop

Talk Your Talk

My dumb face.

I’m on Talk Your Talk with my man Alaska this week. I’m the first guest on this spin off from his usual show, Call Out Culture with Curly Castro and Zilla Rocca, on which I was also the first guest. I did the artwork for their Michael Myers/Nas-themed “Killmatic” episode, too.

In this new one, we talk about my books, new, old, and not-out-yet, as well as a few high-minded social-science theories… and the raps, of course.

You can listen to our brief discussion via the podcasting network of your choice.

Charles Mudede Recommends Boogie Down Predictions

Charles Mudede is a senior editor at The Stranger, “Seattle’s Only Newspaper,” and he’s recently started doing a video series called Charles Mudede’s Book Nook. He writes,

Because a big part of the only life I’ll ever have  is devoted to books, the best thing I can offer during this holiday season is a recommendation of five books you can read by a fake fire (like the one in my cottage) or gift those who happen to be close to your life or who you want to be close to your life.

In the third installment of the series, Charles recommends Boogie Down Predictions, a collection of essays edited by me and published by Strange Attractor Press. See the video below:

Many, many thanks to Charles and The Stranger for recommending this book. We worked very hard on it. Find out more and get your own copy.

Walk This Way

I was in the tenth grade when Run-DMC’s “Walk This Way” came out. I remember hearing it and feeling like something truly unique was happening. Raw, raucous, and rocking. It brought together fans of both traditional rock n’ roll and rebellious hip-hop.

Recently, I pitched the song to a book series specifically about individual songs, but they didn’t agree on the impact or the import of it. Well, while I was factchecking my memory, I found out there’s already a whole book about it! There’s no doubt it was a special moment in music, a new node in a burgeoning network of sound.

Notebook cover I made from the sleeve of Run-DMC’s Raising Hell (1986).

Aerosmith’s original version of “Walk This Way,” from their 1975 record Toys in the Attic, starts with a few measures of just the beat. It’s just the kind of clean drum beat hip-hop DJs scour recordings to find. With two copies of the record, one can loop it back and forth, providing a seamless backbeat to rap over. Run-DMC’s DJ Jam Master Jay had already been using the record in this manner.

In 1986, Aerosmith was in shambles. Their 1985 reunion record Done With Mirrors had not met the expectations of their fans or their label, and their personal lives were in decline due to persisting drug problems. Starting with singer Steven Tyler, they would all enter rehab over the next couple of years. If not, they knew they were likely over as a band. After rehab and collaborating with Run-DMC on “Walk This Way,” Aerosmith followed the song with a string of multi-platinum albums and Top 40 hits, entering the most successful era of their careers and becoming one of the biggest rock bands of the 1990s. It was a miraculous turnaround.

Though they hated the idea at the time, Run-DMC’s version of “Walk This Way” is a testament to the ear of their producer Rick Rubin. His production style, which he’d already used on previous Run-DMC records, as well as records for T La Rock & Jazzy Jay, the Beastie Boys, and LL Cool J, was credited as “reduction” instead of production. He stripped their sound down to its basic elements: boom-bapping 808 drums, classic-rock guitar riffs, the shouted voices of Reverend Run Simmons and Darryl “DMC” McDaniels, and the nimble cuts and scratches of Jam Master Jay.

As a nascent record label mogul and producer, Rubin was only getting started. The iconic sound he developed with early hits like “It’s Yours,” “Rock the Bells,” “(You Gotta) Fight for Your Right (to Party)” and “Walk This Way” keep him in demand to this day. He’s gone on to produce everyone from Public Enemy, Ghetto Boys, Sir Mix-a-Lot, and Kanye West to the Mars Volta, Metallica, Tom Petty, Johnny Cash, Lana Del Rey, and Adele, and he’s redone the reduced style of his early work on everything from Jay-Z’s double-platinum “99 Problems” (2003) to Eminem’s Grammy-nominated “Berzerk” (2013), even appearing in the videos for both songs.

Speaking of, the video for “Walk This Way” was as iconic as the song. It starts as a fight, with Aerosmith practicing loudly in one room, disrupting Run-DMC’s session next door. Run-DMC then turns up the volume on their equipment and launches into their version of “Walk This Way,” confusing the aged rockers. By the chorus, the wall is torn down (inviting more than a few interpretations), and the two groups are ripping through the song together. The video was even parodied in 1994 by the Jon Spencer Blues Explosion on their song “Flavor” which features Beck in the practice space next door.

For better or worse, “Walk This Way” also sparked the further mixture of rap and riffs, giving birth to collaborations between rap groups and rock groups and a start to acts firmly on the fence in between. Public Enemy and Anthrax covered PE’s “Bring the Noise” in 1991. The two groups even toured together that year. I saw them at the University of Alabama at Birmingham in a chocolate-and-peanut-butter package that also included Young Black Teenagers and Primus. In 1993, the infamous Judgement Night soundtrack featured collaborations between Slayer and Ice-T, Sonic Youth and Cypress Hill, and Dinosaur Jr. and Del the Funky Homosapien, among many other embarrassing pairings. And, as if reading “Walk This Way” as a blueprint to success, acts like Limp Bizkit, Linkin Park, and Rage Against the Machine also emerged in the 1990s.

“Walk This Way” was an unavoidable song and an undeniable hit, Run-DMC’s biggest, peaking at #4 on the Billboard chart. It was bigger even than Aerosmith’s original, which just broke the top ten. Run-DMC is one of the core groups of the first recorded era of rap music and hip-hop culture. They were successful and respected before and after this song, but they never saw heights like “Walk This Way.” The song was the nexus of several trajectories and the birth of a hybrid new life form that still stomps around today.
