Melvins is an American experimental sluge metal band that usually perform as a trio. Singer/guitarist Buzz Osborne (aka "King Buzzo") and drummer Dale Crover are constant members, but the band has seen several bass guitarists. They have occasionally added a guest or second guitarist for live performances. The band was named after a grocery clerk at a Thriftway in Montesano, Washington where Osborne also worked as a clerk. "Melvin" was greatly despised by other employees, and the band's members felt it to be an appropriately ridiculous name.
