Napalm Death

Napalm Death are a grindcore/death metal band from Birmingham, England. The band was formed in the village of Meriden near Birmingham, England in 1981 by Nicholas Bullen and Miles Ratledge.

Although other groups had previously played fast and aggressive music, Napalm Death are credited with defining the Grindcore genre through their fusion of punk and metal musical structures, aggressive playing, fast tempos, and deep guttural vocals. The group coined the term ‘Grind’ to describe the music they played in reference to the sound of American post-punk group Swans.
