Audioslave was an American rock supergroup that formed in Los Angeles, California in 2001. It consisted of then-former Soundgarden lead singer/rhythm guitarist Chris Cornell and the then-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.

The band's trademark sound was created by blending 1970s hard rock with 1990s alternative rock. Moreover, Morello incorporated his well-known, unconventional guitar solos into this mix. As with Rage Against the Machine, the band prided themselves on the fact that all sounds on their albums were produced using only guitar, bass, drums and vocals.
