Riot Act is the seventh album from Pearl Jam, released November 2002. The music on Riot Act featured a diverse sound, including songs influenced by folk, art rock, and experimental rock. The lyrics deal with mortality and existentialism, with much influence from both the political climate after the September 11, 2001 terrorist attacks and the accidental death of nine fans during Pearl Jam's performance at the 2000 Roskilde Festival. The band supported the album with a politically charged concert tour in 2003. Riot Act was the band's last album of all-new material for Epic.
