!! The musical band:

* SugarWiki/AwesomeMusic:
** The entirety of ''In the Nightside Eclipse'', which routinely tops "Best BlackMetal Albums Ever" lists as well as being the TropeCodifier for [[SymphonicMetal Symphonic Black Metal]].
** Really, all of their albums, BrokenBase aside. Emperor was an astonishingly consistent band.
** The ending of "Inno a Satana" from their performance at Wacken 2014. Ihsahn and live keyboardist/vocalist Einar Solberg perform a vocal harmony where Einar ends up pulling off a superb type 4 MetalScream.
* BrokenBase: The fandom's stance on the more [[ProgressiveMetal progressive]] direction the band took after ''Anthems''.
*** Better yet: Which album is ''better''?: ''In the Nightside Eclipse'' or ''Anthems to the Welkin at Dusk''?
** It doesn't help that many fans feel uncomfortable about aspects of the band's past. Both Samoth and Faust have both done prison time at some point or another, Faust having done his for murdering a gay man which he still has no real remorse about and Samoth having been involved in one of the Norwegian church burnings. Ihsahn also expressed Social Darwinist views in interviews, claimed that Christianity was a religion for weak people and even justified the Norwegian church burnings (although this last has been subject to FlipFlopOfGod as at other times he's condemned them). Ihsahn however seemed to have dwindled down with these views, especially now in regards to his criticisms towards the Norwegian church burnings, as well as pointing out Euronymous was a rather negative threat to the community with his death threats. Ironically enough, Euronymous wrote the riff for "Ye Entrancemperium" and ''In the Nightside Eclipse'' was dedicated to him.
* EpicRiff: Lots of them. The main riff of "Ye Entrancemperium" stands out, though, which shouldn't be a surprise since it was composed by [[Music/{{Mayhem}} Euronymous]].
* EvenBetterSequel: The more ProgressiveMetal oriented section of the band's fanbase feel that ''Prometheus'' is their best work. Some fans also prefer ''Anthems'' due to the more polished sound.
** ''In the Nightside Eclipse'' is hailed as a classic. ''Anthems to the Welkin at Dusk?'' Even more so.
* FirstInstallmentWins: ''In the Nightside Eclipse'' was their first album, as well as their most beloved and influential.
* OvershadowedByControversy: While the band has not suffered this to the same degree as Music/{{Mayhem}} or Music/{{Burzum}}, many non-fans are primarily aware of the band due to their drummer Faust going to prison for murder, as well as the controversies surrounding Faust’s participation in reunion shows after his release.
* SignatureSong: "I Am the Black Wizards", to the point where Ihsahn doesn't even announce it live these days and just launches into the intro.
* ToughActToFollow: Some believed this was the reason Music/{{Zyklon}} wasn't a worthy successor, despite both being very different. Music/{{Ihsahn}}'s solo work also gets this to some extent, though arguably not as much - it's quite acclaimed in ProgressiveMetal circles, particularly ''The Adversary'' and ''After''.
