Siege is an American hardcore punk band from Weymouth, Massachusetts. Formed in 1981, they were active in the Boston hardcore scene from 1984 to 1985, and reunited briefly in 1991. Guitarist Kurt Habelt and drummer Rob Williams reformed the band in 2016. 　　  　　In its original incarnation, Siege paired extremely fast tempos with vocalist Kevin Mahoney's screeches and growls in their intense style of hardcore. Though little known at the time, the band has posthumously become revered by punk and heavy metal fans worldwide and is now regarded as one of the pioneers of the grindcore and powerviolence subgenres. Subsequent musicians have cited the group as a major influence, including the British grindcore band Napalm Death and the American thrashcore band Dropdead, whose band name was the title of Siege's six-song demo tape.
