Rage Against the Machine is formed

Rage Against the Machine (often shortened to RATM) is an American metal band from Los Angeles, California, formed in 1991.

The band's lineup, unchanged since its formation, consists of vocalist Zack de la Rocha, guitarist Tom Morello, bassist Tim Commerford, and drummer Brad Wilk. Rage Against the Machine is noted for its innovative blend of alternative rock, rap, heavy metal and funk as well as its revolutionary politics and lyrics. Rage Against the Machine drew inspiration from early heavy metal instrumentation, as well as rap acts such as Public Enemy, Urban Dance Squad, and Afrika Bambaataa. The group's music is distinguished primarily by their powerful stage energy, de la Rocha's rhyming styles and Morello's unorthodox guitar techniques.

Integral to their identity as a band, Rage Against the Machine voice revolutionary viewpoints highly critical of the domestic and foreign policies of current and previous US governments. Throughout its existence, RATM and its individual members participated in political protests and other activism to advocate these beliefs. The band primarily saw its music as a vehicle for social activism; de la Rocha explained that "I'm interested in spreading those ideas through art, because music has the power to cross borders, to break military sieges and to establish real dialogue."
