In early 1991, guitarist Tom Morello -- fresh off splitting his metal band Lock Up -- caught Zack de la Rocha freestyling at a Los Angeles club, months after police were filmed beating motorist Rodney King. Morello brought drummer Brad Wilk; de la Rocha brought bassist Tim Commerford. In a San Fernando Valley rehearsal room they built a sound fusing Chuck D-style political fury to a guitar rigged to mimic a DJ's turntable, over a rhythm section drilled in hardcore urgency. Producer Garth Richardson recalled de la Rocha invoking Malcolm X while writing "Killing in the Name"; Morello has called the toggle switch behind that scratch effect his own accident, found because his "uncool" guitar had one knob too many. The 1992 debut turned righteous noise into an arena act, and the song outlived the era it was built to indict, ambushing the UK singles chart in 2009.

MC51960s · Proto-punk / Hard rock
Morello made the connection blunt in 2000: "we're fortunate to have nosebleed seats in the arena built by the MC5, Bob Marley, and Public Enemy." Twenty-five years later he was still saying it, calling Detroit guitarist Wayne Kramer a friend he'd played prison shows alongside and writing that "the MC5 INVENTED punk rock music" -- the raw, confrontational fury Rage inherited wholesale. In 2000 the band made the debt literal, recording MC5's own anthem, produced by Rick Rubin, for the covers album Renegades.

Kick Out the JamsRage Against the Machine
listen forPut the two versions back to back and the debt is structural, not just rhetorical: both open cold, no build, with a shouted command straight into the crowd, and both keep the guitars distorted and buried rather than polished. De la Rocha copies Rob Tyner's phrasing almost note for note on the hook, and Morello leaves in the same live-wire sloppiness Wayne Kramer never smoothed out -- the sound of a band choosing to blow the tape out rather than play it safe.
Public Enemy1980s · Hip hop / Political hip hop / Conscious hip hop
Before Rage existed, Morello named his target directly: "my chief influences were Terminator X and Jam Master J, and I was determined to recreate the record scratching, DJ stuff -- those rich, bizarre textures -- on my guitar," he said of writing songs in his pre-Rage band Electric Sheep. Terminator X's siren-scratch hook on Public Enemy's "Rebel Without a Pause" was exactly that kind of texture -- a DJ turned into a lead instrument -- and Morello set out to build the same effect with a guitar's pickup toggle switch instead of a mixer's fader.

Bulls on ParadeRage Against the Machine
listen forListen for the piercing, siren-like scratch that Public Enemy's DJ Terminator X loops under Chuck D's verses -- a texture pulled from a turntable, not played on an instrument. On "Bulls on Parade," Morello reproduces that exact effect with no DJ in the room: flicking the pickup selector while muting the strings to fake a record being cut, then stretching the resulting stutter with a whammy pedal until it wails like the sample it's imitating.
Run-D.M.C.1980s · Hip-hop / Old-school hip-hop
The other name in that same breath was Jam Master Jay. Guitar.com's account of Morello's pre-Rage songwriting says he was "profoundly influenced by Run-DMC, and DJ Jam Master Jay in particular" even before Rage existed -- evidence the scratch-mimicry idea he'd later chase on guitar had a specific source, not just a genre. Guitar World singles out where it lands hardest: "Bullet In The Head's verse scratches and the thrilling climax of Know Your Enemy's incendiary solo."

Know Your EnemyRage Against the Machine
listen forOn "Peter Piper," Jam Master Jay cuts a nursery-rhyme bell sample into a stuttering, rhythmic scratch that functions like a second verse. Listen for the same stutter at the climax of "Know Your Enemy": Morello isn't soloing in the conventional sense, he's cutting his own guitar signal on and off in short bursts with the toggle switch, chasing the same rhythmic cut-up Jay was doing with vinyl a few years earlier.
