Conception is a ProgressiveMetal band from Roufass, Norway formed in 1989 by Tore Ostby. In 1990, the lineup was rebuilt after their first demo, only the two Ostbys (Tore and vocalist Dag) remained of the initial lineup. When Dag quit later in the year, he was replaced by [[Music/{{Kamelot}} Roy Khan]] as Tore was impressed by his audition and operatic style. Despite their initial short-lived span (about 9 years), Conception proved to be somewhat influential in the ProgressiveMetal genre due to their unique style. Tore went on to form the even more short-lived ARK with [[Music/{{Masterplan}} Jorn Lande]] and Khan went on the join the American PowerMetal band Music/{{Kamelot}}. They reformed as a reunion in 2005 (headlining Prog Power USA, one of the biggest metal festivals in world, that year), and announced in early 2018 that they would be recording a fifth album.

Final Lineup/Reunion Lineup:
* Guitar: Tore Ostby
* Vocals: Roy Khan

* Drums: Arve Heimdal

* The Last Sunset (1991)
* Parallel Minds (1993)
* In Your Multitude (1995)
* Flow (1997)

!!The band provides examples of:
* AlbumIntroTrack: ''Prevision'' on ''The Last Sunset''.
* {{Animorphism}}: The protagonist of ''Fairy Dance'' is turned into a cow.
* ArtificialIntelligence: What the song ''Parallel Minds'' seems to be about.
* ConceptAlbum: ''In Your Multitude'' is one about a missionary leading a religous war while he is starting to doubt his mission.
* CrisisOfFaith: Large parts of ''In Your Multitude''. ''A Million Gods'' is perhaps the strongest example.
* EpicRocking: ''Among Gods'' (10:39), ''In Your Multitude'' (6:39), ''A Million Gods'' (7:45), ''Soliloquy'' (9:07).
* EpicInstrumentalOpener: Several examples, ''Elegy'' being a 2 minute track as an instrumental opener for ''The Last Sunset'''s title track.
* FilkSong: Several on ''Parallel Minds'' and ''Flow'', like the former's title track or the latter's ''Virtual Love Story''.
* HeavyMithril: A lot of it on ''The Last Sunset'', the most obvious example being ''Fairy Dance''. They toned it down on ''Parallel Minds'' onwards.
* IntercourseWithYou: ''Angel (Come Walk With Me)'' is borderline this, what with strangely ([[HomoeroticSubtext homo]])erotic lyrics and the vocalist sighing and moaning throughout the song.
* LastNoteNightmare: ''Soliloquy'', again.
* LighterAndSofter: ''Flow'' as a follow-up to ''In Your Multitude''.
* LyricalDissonance: ''Silent Crying'' is a [[Main/MohsScaleOfRockAndMetalHardness soft (3-4)]], soulful ballad about what is very heavily implied to be [[spoiler: child molestation/rape]].
* NewSoundAlbum: ''Flow'' to some extent, at least considering how the three percursors more or less maintained the same style.
* NotChristianRock: Their lyrics have a lot of references to religion and spirituality, as well as the names of some songs (''Gethsemane'', ''Angel'', ''Cardinal Sin'') and even the band's very name, but they seem to never have explicitly identified as a Christian metal band.
** ''My Decision'' even seems to be a soft example of a ReligionRantSong.
* OneManSong: Missionary Man.
* PowerBallad: ''The Last Sunset'', ''Silent Crying'', ''Sanctuary'', ''Cry'', and ''Hold On''.
* ProgressiveMetal: They fall into this genre, often bordering on PowerMetal.
* ScareChord: The album ''In Your Multitude'' begins with one.
* TitleTrack: Every album has one.
* VoiceTypes: Roy Khan is a tenor, but in his work with ''Conception'' he makes wide use of counter-tenor, as well, which is absent from his ''Kamelot''-era recordings.
