Hellhammer was an early black metal band, popular briefly in Europe in the mid-1980s. Tom Warrior (later of Celtic Frost), Bruce Day and Steve Warrior formed the band in 1982 (1982 in music). A demo tape called Apocalyptic Raids became an underground, word-of-mouth hit and was eventually released by Noise Records (1984 in music). By then, the band had already broken up, but the recording was one of the original black metal recordings, and spawned a legion of imitators, playing doom metal, Norwegian death metal and industrial metal.
