Okay, I am cheating a little bit here. Rather than have separate entries for Celtic Frost, Hellhammer, and Triptykon, I am choosing an umbrella listing for all three. I think that is probably the best way to handle this because all three bands were driven by Tom G. Warrior and all had similar elements, although the major defining aspect of their music was growth and evolution. Hellhammer was the starting point. That band played a mix of metal and punk that eventually came to help influence the thrash, black, and death metal scenes. Then Hellhammer became Celtic Frost which built upon the relatively simple ideas of Hellhammer and fleshed them out, and made them more complex. But Celtic Frost was not content to simply rest on their laurels and make the same album time after time. They experimented heavily with non-metal influences. Then they declined spectacularly in quality finally breaking up. Celtic Frost reunited and put out a simply stunning but very hard to categorize album in 2006. Then some problems reappeared and Warrior formed Triptykon which built on the Frost reunion album.
Celtic Frost was massively influential on three different metal scenes and undoubtedly put out some fantastic music. Better yet, their good albums still sound fresh and relevant today. Not bad for albums nearly 30 years old.
