The Melvins are an American band that formed in 1983. They usually perform as a trio, but in recent years have performed as a four piece with two drummers. Since 1984, singer and guitarist Buzz Osborne (also known as King Buzzo) and drummer Dale Crover have been the band's constant members. The band was named after a supervisor at a Thriftway in Montesano, Washington, where Osborne also worked as a clerk. "Melvin" was despised by other employees, and the band's members felt it to be an appropriately ridiculous name. The Melvins' music is influenced by Black Flag's mix of punk and metal on their album My War, and other slow punk acts like Swans, Flipper and Wipers, but also by some hard rock and metal bands as Kiss and Alice Cooper; however, their idiosyncratic approach, bizarre sense of humor, and experimentation make neat categorization difficult. Osborne has also stated that his guitar playing is more influenced by Black Flag than Black Sabbath, whom they are often compared with. They often favor very slow tempos, and their sludgy sound was a strong influence on music, especially Nirvana, Soundgarden, Green River, and many other bands from Seattle. These bands, however, tended to use more conventional musical structures with this sound. Melvins have also influenced many bands outside the Seattle grunge scene, including Tool, who are personal friends with the band, Boris, who took their name from the title of a Melvins song, Mastodon, Neurosis, Eyehategod, and Isis.
