Soundgarden disbanded in 1997 due to tensions in the band, and Cornell pursued a solo career. In 2001, he joined Audioslave, a supergroup that included former Rage Against the Machine members Tom Morello, Brad Wilk and Tim Commerford. The band released three albums in six years and also performed at a concert billed as Cuba's first outdoor rock concert by an American band, though some Cuban artists have disputed that claim.
