The development of the Seattle independent record label Sub Pop is tied closely to Soundgarden, since Sub Pop co-founder Jonathan Poneman funded Soundgarden's early releases, and the band's success led to the expansion of Sub Pop as a serious record label. Nirvana frontman Kurt Cobain was a fan of Soundgarden's music, and reportedly Soundgarden's involvement with Sub Pop influenced Cobain to sign Nirvana with the label. Cobain also stated that Soundgarden was one of the only Seattle bands that he liked along with Tad and Mudhoney. In rare footage from the 2015 documentary "", Cobain can be seen impersonating Chris Cornell singing "Outshined". Alice in Chains guitarist and vocalist, Jerry Cantrell stated that Soundgarden was a big influence on his band.
