One of the more famous BlackMetal bands, possibly the most famous behind Music/{{Mayhem}}, and the ones responsible for the genre's stereotypical image.

Immortal was formed by Abbath and Demonaz Doom Occulta after their previous band, Amputation, didn't take off. The band's beginnings can also be traced back to the death metal band Old Funeral, of which both Abbath and Demonaz were members.

Their earlier releases were in a more traditional black metal style, but as of the acclaimed ''At the Heart of Winter'', they have fused black metal with elements of German ThrashMetal. Euronymous of Music/{{Mayhem}} is credited for getting Abbath into black metal and as a result, Abbath getting the infamous [[Music/{{Burzum}} Varg Vikernes]] into black metal as well; however, despite these associations, Immortal's primary members have never been involved in the more controversial activities of some of their contemporaries in black metal, and their lyrics have also never involved the religious or political ideologies often associated with the scene.

The band split up in 2003 for various personal reasons. Afterwards, Abbath formed the {{Supergroup}} I with various other musicians from the Norwegian black metal scene (including members of such groups as Music/{{Enslaved}} and Music/{{Gorgoroth}}); the group released the album ''Between Two Worlds'' in 2006 to critical acclaim. The band's style is generally considered to be a fusion of BlackMetal with the style of Music/{{Motorhead}}, also referred to as "black and roll", and has been considered an influence on the later work of other bands, notably Satyricon. I is currently on hiatus.

Immortal reformed in 2007 for a string of live performances; after the reunion, the band decided to reform the band on a permanent basis, releasing the album ''All Shall Fall'' in 2009. However, internal conflicts between the band members resulting from tumultuous recording sessions for the band's ninth album resulted in a second disbandment in 2015. What exactly occurred during the sessions [[RashomonStyle seems to depend upon whom you believe]], but in the wake of the disbandment, Abbath started a new band [[EgocentricTeamNaming in his name]] (which admittedly is a well known quantity in the world of black metal, so it's a sensible business decision) with bassist [[Music/{{Gorgoroth}} King ov Hell]] and drummer Baard Kolstad.

On August 14, 2015, Demonaz and Horgh announced that they had reconvened the band and that they will continue without Abbath. Demonaz took over the lead vocals and also returned to guitar. Abbath's first, self-titled album was released in January 2016 through Season of Mist and apparently consists largely of material written for what was supposed to be Immortal's new album before the split. Meanwhile Demonaz and Horgh decided to write and record Immortal's ninth album, purpoted for release by Nuclear Blast. It currently remains to be seen how much of the material on Immortal's upcoming album dates back to the sessions from when Abbath was still in the band, whether his contributions from those sessions will be subjected to an OrwellianRetcon. In January 2018 they announced to have finished the recording.

Please do not confuse them with [[Film/{{Immortal}} the film of the same name]] or, if such were even possible, "Fanfic/MyImmortal".

!! Tropes that apply to Immortal:

* AbbeyRoadCrossing: [[http://i.imgur.com/zf67IcW.jpg Abbath Road]].
* TheBandMinusTheFace: When they reformed without Abbath.
* BlackMetal: The TropeCodifier in terms of fashion and imagery.
* CallBack: The name for their album ''Sons of Northern Darkness'' is taken from lyrics to the song "Storming Through Red Clouds and Holocaustwinds" from their second album, ''Pure Holocaust''.
* CareerEndingInjury: Demonaz Doom Occulta was forced to stop playing guitar due to developing tendinitis in his arms in 1997. He still writes the band's lyrics and is considered an active member by the band itself. In 2015, following Abbath's departure, Demonaz replaced him as the new vocalist and started playing guitar again.
* CoverVersion: They covered "From the Dark Past" on the Music/{{Mayhem}} tribute album ''Originators of the Northern Darkness''.
* EarlyInstallmentWeirdness: Their first album was somewhat slower and more DeathMetal-influenced than their later work tended to be, and had a few acoustic guitar passages as well.
* EchoingAcoustics: This started to be a major element of their sound with ''Pure Holocaust'' and they haven't toned it down much since.
* EpicRocking: Most of their songs, especially since they shifted their style to Melodic Black/Thrash Metal on ''At the Heart of Winter'', which consisted exclusively of this trope. All of their albums since ''Blizzard Beasts'' have contained at least one example of this, with ''Sons of Northern Darkness'' taking the prize for largest number of epic songs after ''Heart of Winter''.
* GrimUpNorth: Their primary lyrical content and band image.
* HeavyMithril: Instead of focusing on Satanism like their peers, Immortal's lyrics focus on an imaginary world called Blashyrkh, plagued by war and suffering and ruled over by the Mighty Ravendark.
* LeadBassist: Abbath was type 2 until 1998. When Demonaz became unable to play guitar anymore, instead of finding new guitarist, Abbath switched to this instrument and Immortal found new bassist.
** LeadDrummer: Abbath played drums on ''Pure Holocaust'' and ''Battles in the North''.
* LongTitle: Honestly, at least half of them on the first three albums and quite a few after that, but "Storming Through Red Clouds and Holocaustwinds" has to take the cake.
* LoudnessWar: This has affected all their releases from ''Battles in the North'' onwards (''Battles'' also got a remaster which was even louder than the original release). ''At the Heart of Winter'' and ''Damned in Black'' (both [=DR5=]) are probably the worst examples of this in their discography, and ''All Shall Fall'' and I's ''Between Two Worlds'' stand out as well (both [=DR6=]). Abbath's solo album is also affected, although by modern standards it's actually fairly quiet (it's [=DR7=] and still moderately clipped, but many listeners will probably not be able to tell); the same goes for ''Sons of Northern Darkness'', which is more dynamic than most of Immortal's other late-period releases at [=DR7=] and also not as badly clipped as many of them. Their first two albums remain unaffected even in modern issues; ''Pure Holocaust'' in particular stands out as a sterling example of the way black metal still ought to sound.
* MohsScaleOfRockAndMetalHardness: ''Diabolical Fullmoon Mysticism'' is mostly a 9 as a result of EarlyInstallmentWeirdness, ''Holocaust'' through ''Beasts'' are pure, ''hard'' 10 bordering on 11 (due to the [[EchoingAcoustics production]] and the near-constant use of blastbeats) and everything from ''At the Heart of Winter'' on is in the 9-low 10 range.
* NewSoundAlbum: Two of them -- ''Pure Holocaust'' for introducing the insanely fast, blastbeat-heavy style they played for most of the '90s and ''At the Heart of Winter'', which began the [[EpicRocking epic]], ThrashMetal --influenced era of their career.
* NoEnding: Several songs on ''Battles in the North'' (specifically, the first five and track seven) end very abruptly.
* RockMeAsmodeus: Averted, which is rare for second-wave black metal.
* SeriousBusiness: Notably averted, at least for the band. Black metal bands tend to take themselves very seriously; Immortal do not.
* SincerestFormOfFlattery: They've made no secret of Music/{{Bathory}}'s influence on them, dedicating one song on I's ''Between Two Worlds'' to Quorthon. With ''All Shall Fall'' they take this UpToEleven as several songs sound like they could have been outtakes from ''Blood Fire Death''. This is hardly a bad thing; it's hard to imagine a better tribute to Quorthon's influence over black metal.
* StageNames: Nearly every member past and present has one.
* StartMyOwn: Abbath started his own solo band after leaving Immortal.
* TokenGoodTeammate: They count to a tee, since they were neither involved in any of the controversial activities of their contemporaries, nor are their lyrics about anything political or religious, in the second wave of black metal.
* UncommonTime: They like this trope a lot. As an early example, one riff of "Cold Winds of Funeral Dust" has a measure of 6/4 followed by a measure of 7/4. An exhaustive list would take a long time to compile; they generally use it at least [[OnceAnEpisode once an album]] and often times more than that. It's one of the reasons they have a reputation as one of the most technical and musically complex second-wave acts.
* VocalEvolution: Compare Abbath's vocals on the earlier albums like ''Pure Holocaust'' and ''Battles in the North'' to the ones on later albums like ''Sons of Northern Darkness'' and ''All Shall Fall''. Yep.
