Only one influence need be mentioned when discussing Germany's Warhammer: Hellhammer. No, not the Norwegian black metal drummer, but rather the long-disbanded group from Switzerland that served as the template to one of the '80s most innovative and avantgarde bands: Celtic Frost. Hellhammer only released one record, an EP called Apocalyptic Raids, but that solitary release was more than enough to plant the musical seed in a small group of aspiring musicians that would eventually germinate into Warhammer.
