Audioslave was an American hard rock supergroup that was formed in Los Angeles, California in 2001. It consisted of ex-Soundgarden frontman, rhythm guitarist, and drummer Chris Cornell and the former instrumentalists of Rage Against the Machine: Tom Morello (guitar), Tim Commerford (bass and backing vocals) and Brad Wilk (drums). Critics initially described Audioslave as an amalgamation of Rage Against the Machine and Soundgarden, but by the band's second album, Out of Exile, it was noted that they had established a separate identity.
