Celtic Frost is/was an extreme metal band from Zurich, Switzerland. It is, along with Music/{{Bathory}} and Music/{{Helloween}}, one of the most influential metal bands to come out of Europe. Celtic Frost (along with Music/{{Bathory}}) was heavily influential on the extreme metal scene, particularly the {{black metal}} scene. Some have regarded Celtic Frost as a "missing link" between thrash metal and black metal.

Celtic Frost was founded by guitarist Tom Gabriel Fischer after he had left the band Hellhammer. He formed the band with Martin Eric Ain and Stephen Priestly to record the mini-LP ''Morbid Tales'', which garnered interest in the undeground metal scene. A year later, they released the highly influential ''To Mega Therion''. With full attention on them, they released the highly avant-garde ''Into the Pandemonium'', which featured classical instruments, operatic female vocals, and sampling. Despite this, ''Into the Pandemonium'' is still held in high regards by fans. They eventually went on a tour to America. Because of this and many internal and external conflicts in the band, they released the album ''Cold Lake''. This album adopted many of the hair metal elements that were being used by many American metal bands at the time. This alienated their strong fanbase in Europe yet the album sold well in America. They soon released the album ''Vanity / Nemesis'' which combined the elements of ''Cold Lake'' and their earlier albums, but they still could not regain the popularity they had years before. Their final album they released before breaking up was ''Parched With Thirst I Am Dying'', which contained unreleased material, re-recordings of older songs, studio versions. Their final album was to be titled ''Under Apollyon's Sun'', but it never came to fruition. They eventually reunited in 2001 and began writing material for a new album, which resulted in ''Monotheist'', a return to their original style, but [[DarkerAndEdgier much darker]], with elements of DoomMetal. This was only short lived, because as of 2008, Tom and Martin decided to lay Celtic Frost to rest for good, with Martin's tragic passing on October 22nd, 2017 confirming it for good.

!!This band contains examples of...

* AlbumIntroTrack: "Innocence and Wrath" is one of the most famous in metal, an epic, bombastic orchestral track that sets up the atmosphere of the album perfectly.
* AwesomeMcCoolName: Tom Gabriel Warrior and Martin Eric Ain. Tom's real name, Thomas Gabriel Fischer, is only slightly less so.
* BadassBaritone: Tom G. Warrior has a very deep singing voice.
* ContemptibleCover: ''Emperor's Return'', which looks like something Frank Frazetta would draw.
* CoverVersion: They have covered "Mexican Radio" by Wall of Voodoo, "This Island Earth" by Bryan Ferry and "Heroes" by Music/DavidBowie.
* DarkerAndEdgier: Celtic Frost was heavier than pretty much every other metal band when they first formed, which ultimately led to the creation of black and death metal. Within the band's discography itself, ''Monotheist'' is this after the relatively lighter ''Cold Lake'' and ''Vanity/Nemesis'', being a dark and gritty gothic metal record with Satanic lyrical themes.
* DramaticTimpani: Used on "Innocence and Wrath" and "Dawn of Megiddo".
* EpicInstrumentalOpener: "Innocence and Wrath" is a particularly bombastic example.
* EpicRocking: Most of their longer songs were 6 minutes long, but ''Monotheist'' takes it to a new level, with "Triptych: II. Synagoga Satanae" being the absolute longest, spanning at 14:23 minutes (and technically, it's only the second part of a longer three-part song!)
* GenreShift: Their original sound was very similar to {{Music/Venom}} [[BlackMetal black]] / [[ThrashMetal thrash]] metal with some DeathMetal elements. ''Into the Pandemonium'' was somewhat less dark and had avant-garde influences, ''Cold Lake'' was GlamMetal mixed with GothRock, ''Vanity/Nemesis'' was ThrashMetal and finally ''Monotheist'' was GothicMetal and DoomMetal.
* {{Goth}}: The band's aesthetic around the time of ''Monotheist'' (and arguably since ''Into the Pandaemonium'').
* GutturalGrowler: Tom's vocals, most of the time.
* HeavyMithril: They have a lot of fantasy influenced lyrics, particularly on ''To Mega Therion.''
* IAmTheBand: Arguably Tom G. Warrior, as the frontman and primary composer of the band. Martin Eric Ain was also an important force in the band, but Tom was the only one with the band for its whole existence.
* LargeHam: Tom's vocals are ''quite'' enthusiastic.
* LeadBassist: Martin Eric Ain is a type B and C.
* LongTitle: "A Dying God Coming Into Human Flesh".
** album title, ''Parched With Thirst Am I, and Dying''
* MohsScaleOfRockAndMetalHardness: Generally stuck to a 9; occasionally lighter interludes, intros, and outros appear for contrast.
* PunctuatedForEmphasis: From "Wine in My Hand".
--> '''Third! From! The! Sun!'''
* RatedMForManly: Most of their music, but especially ''To Mega Therion'', which has been described as "the musical equivalent of ''Franchise/ConanTheBarbarian''".
* SopranoAndGravel: Used in a few songs on ''Monotheist''
** Celtic Frost helped inspire the genre with a couple tracks from ''To Megatherion'' and ''Into the Pandaemonium'', and the song "Return to the Eve" (along with Venom's "Welcome to Hell") may be among the earliest examples of this style of song.
* SpiritualSuccessor:
** Tom Fischer's new band, Triptykon, was styled to continue in pretty much the exact same direction as ''Monotheist'' era Celtic Frost.
** Celtic Frost itself is somewhat of a spiritual successor to Tom Fischer and Martin Eric Ain's previous band, Hellhammer.
* ScrewTheMoneyIHaveRules: In 2014, Tom Fischer and Martin Eric Ain were offered $140,000 to reform the band for an hour at Wacken Open Air. They immediately declined.
* SurprisinglyGentleSong: The sections of the Requiem featured on multiple albums, as well as the bonus track, "Incantation Against You."
* StepUpToTheMicrophone: Martin on "A Dying God Coming Into Human Flesh" and "Triptych I:Tottengot", both from ''Monotheist''.
