Singer and guitarist Tom Gabriel Fischer announced his departure from Celtic Frost on the 9th of April, 2008, due to "the irresolvable, severe erosion of the personal basis so urgently required to collaborate within a band so unique, volatile, and ambitious." It was confirmed in a joint statement by Fischer and Martin Ain in September that year that Celtic Frost had been disbanded again.
Tom Gabriel Fischer's signature Ibanez Iceman guitar was designed by H.R. Giger.
Tom G. Warrior and Martin Ain formed Celtic Frost after the breakup of Hellhammer.
