Formed in Switzerland in 1984 from the ashes of the thrash metal-inspired Hellhammer, Celtic Frosts focal point was Thomas Gabriel Warrior (Thomas Gabriel Fischer, 19 July 1966, Zurich, Switzerland; guitar, vocals). Together with Martin Eric Ain (bass) and Stephen Priestly (drums), the groups 1984 debut was a thrash metal landmark, with guttural vocals splintering the grim music. Ain was replaced by bass player Dominic Steiner for To Mega Therion, while Reed St. Mark was drummer for Emperors Return. Their next album, Into The Pandemonium, was Celtic Frosts legacy to the metal world, a major work that has been loosely described as avant garde thrash. It marked the return of Ain as well as the introduction of second guitarist Ron Marks. Cold Lake was much more mainstream and featured the return of Priestly (drums), alongside Curt Victor Bryant (bass) and Oliver Amberg (guitar). Following a glam rock bent, it proved too much of a departure from their natural sound to be a success, and fans deserted them. The bands popularity enjoyed a slight resurgence after the much improved Vanity/Nemesis.
In the early 90s St. Mark rejoined the band after a spell with Mindfunk, with the promise of new material in the tradition of their early efforts. This never transpired and the band folded. Fischer returned with a new outfit, Apollyon Sun in 1998. In the new millennium Fischer and Ain began writing songs together. They re-formed Celtic Frost with drummer Franco Sesa and released their first album in 14 years.
