The Melvins are an American rock band that formed in 1983 in Montesano, Washington. They have mostly performed as a trio, as well as a quartet with two drummers in recent years.Their early work was key to the development of both grunge and sludge metal. Generally considered as a sludge metal, grunge,experimental rock, alternative metal and doom metal band, Melvins explored a variety of different styles throughout its career, including noise rock,dark ambient, noise, jazz-rock, avant-garde music, electroacoustic music and punk country. Initially starting out as a hardcore punk act, their sound eventually started to absorb influences by Black Flag's mix of punk and metal, slow punk acts like Flipper and the Wipers, industrial music pioneers Throbbing Gristleand also by hard rock and metal bands such as Kiss and Alice Cooper. Since the 1990s, they have occasionally touched on electronic music, as on Prick , Colossus of Destiny and Pigs of the Roman Empire -- the latter a collaboration with dark ambient pioneer Lustmord.
