Pearl Jam entered Seattle's London Bridge Studios in March 1991 to record their debut album, Ten. Drummer Dave Krusen left the band in May 1991 after checking himself into rehabilitation and was replaced by Matt Chamberlain, but after just a handful of gigs Chamberlain left too and was superseded by Dave Abbruzzese, who played the rest of Pearl Jam's live shows supporting Ten. Released on August 27, 1991, Ten contained eleven tracks dealing with dark subjects like depression, suicide, loneliness, and murder.
