Soundgarden was one of the seminal creators of grunge, a style of alternative rock that developed in Seattle, and was the first of a number of grunge bands to sign to the record label Sub Pop. Soundgarden was also one of the first grunge bands to sign to a major label (A&M Records in 1989), though they did not achieve commercial success until they popularized the genre in the early 1990s with Seattle contemporaries Alice in Chains, Pearl Jam, and Nirvana.
