Rage Against the Machine earned acclaim from disenfranchised fans (and not insignificant derision from critics) for their bombastic, fiercely polemical music, which brewed sloganeering leftist rants against corporate America, cultural imperialism, and government oppression into a Molotov cocktail of punk, hip-hop, and thrash. Rage formed in Los Angeles in the early '90s out of the wreckage of a number of local groups: vocalist Zack de la Rocha (the son of Chicano political artist Beto) emerged from the bands Headstance, Farside, and Inside Out; guitarist Tom Morello (the nephew of Jomo Kenyatta, the first Kenyan president) originated in Lock Up; and drummer Brad Wilk played with future Pearl Jam frontman Eddie Vedder. Rounded out by bassist Tim Bob (aka Tim C., born Tim Commerford), a childhood friend of de la Rocha's, Rage debuted in 1992 with a self-released, self-titled 12-song cassette featuring the song "Bullet in the Head," which became a hit when reissued as a single later in the year.
