* AffectionateParody: The video for "Cockroach King" is one of the video for "Bohemian Rhapsody".

* ConceptAlbum: ''Aquarius'' and ''Visions'' (as detailed under RockOpera below), as well as the duology of ''Vector'' and ''Virus'' (forming an origin story for the Cockroach King).
* ContinuityNod: The melody from "The Path" is repeated throughout ''The Mountain''. "Messiah Complex" contains many nods to previous songs on ''Virus'' and ''Vector'', as well as to "Cockroach King" (off ''The Mountain'').

* EpicRocking: The average length of their songs currently stands at 8:44. Each album has at least one song that passes the 10-minute mark:

** ''Virus'' has "Carousel" (10:29) and the 5 part "Messiah Complex" suite, which clocks in at 17 minutes total.

* ProgressiveMetal[=/=]ProgressiveRock: Depending on the release. ''Aquarius'', ''Visions'', ''Vector'', and ''Virus'' are their more metal releases, while ''The Mountain'', ''Restoration'', and ''Affinity'' lean [[LighterAndSofter a little more toward]] ProgressiveRock (although they are not without their share of heavy songs).
* RearrangeTheSong: ''Restoration'' contains heavily reworked versions of songs from their demo, ''Enter the 5th Dimension''. Guitarist Charlie Griffiths stated in an interview that merely rerecording the old tracks would feel dishonest, as half of the present lineup (including him) did not play on the originals, and that the ''Restoration'' versions are now the definitive ones in the band's eyes.

* BilingualBonus: "Ectobius Rex", the last part of the "Messiah Complex" suite from ''Virus''. ''Ectobius'' is a genus of cockroaches, and "rex" is Latin for "king". Thus, "Ectobius Rex" translates to "Cockroach King" - which is appropriate, given that it (and the album as a whole) features prominent {{Call Back}}s to that song.

* ConceptAlbum: ''Aquarius'' and ''Visions'', as well as companion albums ''Vector'' and ''Virus''.

** ''Aquarius'' has "The Point of No Return" (11:27), "Streams" (10:14), "Aquarium" (10:40), and "Celestial Exilir" (16:56).

In 2014, the band released an EP titled ''Restoration'' containing updates of a select few songs from their demo, ''Enter the Fifth Dimension''. Their sixth full studio album, ''Virus'', was released on July 24, 2020.

* EpicRocking: The average length of their songs currently stands at 8:44. Each album has several songs that hit above the 10-minute mark:

** ''Vector'' has "Veil" (12:35)

* NeoclassicalPunkZydecoRockabilly: They've incorporated elements of ProgressiveMetal, ProgressiveRock, Folk, Jazz, Film Scores, ACappella, and Glitch Hop in their music. Sometimes within one song.

* Raymond Hearne - drums, tuba (2007-)

* Peter Jones - keyboards (2007-2008)

* MohsScaleOfRockAndMetalHardness: ''Visions'' and ''Aquarius'' are usually around a 7 or 8, ''The Mountain'' is around a 6 or 7, with a few songs hitting 8. Some songs can get as heavy as 9 (i.e. the growled parts of ''Aquarius'' and the heavier parts of "Falling Back to Earth"), or as low as a 1 ("As Death Embraces").

* Diego Tejeida - keyboards (2008-)

* AccentUponTheWrongSyllable: The bridge of "Somebody" loops the nine-syllable "I wish I could have been somebody" through a ten-note melody, leading to the phrase becoming more displaced as it goes on ("'''I''' wish I could have '''been''' somebody[=/=]I '''wish''' I could have been '''some'''body"), inevitably leading to the high points of the melody falling in odd places after the first couple iterations.
