Rage Against the Machine is a Grammy Award-winning rap metal band, formed in 1991 in Los Angeles, California, United States. The band's line-up comprises vocalist Zack de la Rocha, guitarist Tom Morello, bassist Tim Commerford and drummer Brad Wilk. Critics have noted Rage Against the Machine for its "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 Against the Machine drew inspiration from early heavy metal instrumentation, as well as rap acts such as Afrika Bambaataa. Public Enemy and Urban Dance Squad. As of 2009, they have sold over 14 million records worldwide.
Rage Against the Machine's second album, Evil Empire, entered Billboard's Top 200 chart at number one in 1996, and subsequently rose to triple platinum status. The song "Bulls on Parade" was performed on Saturday Night Live in April 1996. Their planned two-song performance was cut to one song when the band attempted to hang inverted US flags from their amplifiers ("a sign of distress or great danger"), a protest against having Republican presidential candidate Steve Forbes as guest host on the program that night.
