Rage Against the Machine (sometimes shortened to RATM or Rage) is an American rap rock band, formed in Los Angeles, California in 1991. The band's lineup, unchanged since 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 blend of punk rock, rap, heavy metal, and funk as well as its revolutionary politics and lyrics. Rage Against the Machine drew inspiration from early 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.

Reunion
On April 14, 2007, Morello and de la Rocha reunited onstage early to perform a brief acoustic set at a Coalition of Immokalee Workers rally in downtown Chicago. Morello described the event as "very exciting for everybody in the room, myself included."This was followed by the scheduled Coachella performance on Sunday, April 29 where the band staged a much anticipated performance in front of an EZLN backdrop to the largest crowds of the festival.
