セルティック・フロスト
Apollyon Sun was a Swiss industrial metal band formed by singer/guitarist Tom Gabriel Fischer and guitarist Erol Unala in early 1995, after the termination of Celtic Frost, Fischer's prior group. The group was unofficially dissolved in 2001 when Fischer invited Erol Unala to contribute to the reformation of Celtic Frost. Their name is taken from the Celtic Frost demo "Under Apollyon's Sun".
