Rage Against the Machine is an American rock band from Los Angeles, California. Formed in 1991, the group consists of vocalist Zack de la Rocha, bassist and backing vocalist Tim Commerford, guitarist Tom Morello and drummer Brad Wilk. They draw inspiration from early heavy metal instrumentation, as well as rap acts such as Afrika Bambaataa, Public Enemy, the Beastie Boys and Dutch crossover band Urban Dance Squad. Rage Against the Machine is best known for its leftist political views, which are expressed in many of its songs. As of 2010, they have sold over 16 million records worldwide. In 1992, the band released its self-titled debut album, which became a commercial and critical success, leading to a slot in the 1993 Lollapalooza festival, and is often cited to be one of the greatest and most influential rock albums of all time. In 2003, the album was ranked number 368 on Rolling Stone magazine's list of the 500 greatest albums of all time.
