Matt Cameron became the band 's full-time drummer in 1986 , while bassist Ben Shepherd became a permanent replacement for Yamamoto in 1990 . Soundgarden was the first grunge band to sign to a major label ( A&M Records in 1988 ) , though the band did not achieve commercial success until they popularized the genre in the early 1990s with Seattle contemporaries Pearl Jam , Nirvana , and Alice in Chains . In 1997 , the band broke up due to internal strife over its creative direction .
