Deerhoof is an American independent music group formed in San Francisco in 1994. While it began as an improvisational bass/harmonica solo project of Rob Fisk (subsequently in 7 Year Rabbit Cycle, Common Eider, King Eider), it currently consists of founding drummer Greg Saunier, bassist and singer Satomi Matsuzaki, and guitarists John Dieterich and Ed Rodriguez. Initially performing improvised noise punk, Deerhoof became widely renowned and influential in the 2000s through self-produced creative output combining "noise, sugary melodies, and an experimental spirit into utterly distinctive music".
