A ProgressiveMetal band with PowerMetal and neo-classical metal elements from New Jersey formed in 1993. Often compared to Music/DreamTheater, they are considered one of the most important bands in progressive metal. They have become known partly thanks to their 24 minute symphonic/progressive metal rendition of Homer's ''The Odyssey''.

Could probably use a better description.

[[AC:This band may exhibit the following tropes:]]
* AltumVidetur: The title of the song "Revelation (Divus Pennae Ex Tragoedia)", whose subtitle and parts of its melody are based on The Divine Wings of Tragedy. They probably just looked up each word in an English-Latin dictionary as it's not even proper grammar. For the record, the grammatically correct phrase would be "Pennae Divae Tragoediae".
** Several tracks on ''V: The New Mythology Suite'' have Latin lyrics.
* ArcNumber: Five on ''V: The New Mythology Suite'' (hence the name).
* BlindIdiotTranslation: Song titles. One song has "Divus Pennae ex Tragoedia" in its name, presumably meaning "Divine Wings of Tragedy" (in reference to a previous album and song). It actually means "a rich man of the feathers tragedy out of". In other words, complete jibberish.
** Another, "Oculus ex Inferni" intended to mean "Eye of the Dead," actually says "Eye out of of The Dead Man".
* TheChosenOne: The child (Ma'at) in the story of ''V: The New Mythology Suite''.
* ChronologicalAlbumTitle: ''V: The New Mythology Suite''
* ConceptAlbum: ''V: The New Mythology Suite'', ''Iconoclast'', and arguably ''Paradise Lost''.
* DarkIsEvil: ''V: The New Mythology Suite'' uses this heavily.
* {{Determinator}}: Used quite often throughout their discography, given the Romanticist nature of their songs, but most notable on "Accolade II", with each verse and the chorus ending with lines show casing epic macho resolve.
* DarkerAndEdgier: Their music became much heavier throughout their discography. Compare some of their songs from ''The Divine Wings of Tragedy'' to their newer work, such as ''Paradise Lost'' and especially ''Iconoclast''.
* EpicRocking: Lots of it. Their more notable examples are:
** "A Lesson Before Dying" from their self-titled album is 12:07.
** "The Edge of Forever" from ''The Damnation Game'' is nearly nine minutes.
** "The Accolade" is 9:51 and "The Divine Wings of Tragedy" is 20:42, both from ''The Divine Wings of Tragedy''.
** "Church of the Machine" and "Through the Looking Glass" from ''Twilight in Olympus'' are 8:57 and 13:06, respectively.
** "Rediscovery (Part II) - The New Mythology" from ''V: The New Mythology Suite'' is 12:01.
** ''The Odyssey'''s title track is their longest song to date, running at 24 minutes.
** "Revelation (Divus Pennae ex Tragoedia)" from ''Paradise Lost'' is 9:17.
** ''Iconoclast'''s title track is 10:53. "When All Is Lost" is 9:10 and "Reign in Madness" is 8:37, both from the same album.
* FanNickname: Russell is known as "Sir Russell Allen" by some fans.
** Goes a bit beyond a Fan Nickname when on Star One's live album he's credited with the above name.
*** It was given to him by fans.
* FilkSong: Quite a few of their songs are based upon mythological tales or fantasy stories, like "Lady in the Snow", "The Divine Wings of Tragedy", "Through the Looking Glass", "The Odyssey", and naturally, the entire ''Paradise Lost'' album.
* GratuitousPanning: When you own your own recording studio, why not?
* HeavyMithril: They seem to have a liking for Greek Mythology as evidenced by ''Twilight in Olympus'' and the title track of ''The Odyssey''. ''Iconoclast'' has sci-fi themes.
* LargeHam: Sir Russell Allen.
* LastOfHerKind: The child in ''V: The New Mythology Suite'''s story is the only survivor of Atlantis. [[spoiler:Then she dies.]]
* LeadBassist: Michael Lepond is a Type A.
* MetalScream: All over the place. Russell Allen is fond of them.
* MohsScaleOfRockAndMetalHardness: For the most part, about a 7, but a step or two higher or lower isn't unheard of. Their later work can go up to an 8 or even a soft 9 at times.
* NeoclassicalPunkZydecoRockabilly: Not evident with their first two albums, but after ''The Divine Wings of Tragedy'', their catalogue showed a mixture of influences ranging from the standard progressive and metal fair to more obscure influences like thrash metal, symphonic, classical and even a bit of jazz.
* NewSoundAlbum: Starting with ''Paradise Lost'', they began to lose some of their neoclassical and progressive influences and took on a harder-edged metal sound.
** One could even say that this started with ''The Odyssey", as their music got a bit heavier with this release in comparison to their previous works.
* OneOfUs: Russel Allan has admitted to something of a love for videogames.
* OneSteveLimit: Thoroughly averted with three Michaels in the lineup.
* PrecisionFStrike: "Dehumanized". "Hit the switch, you ''son of a '''bitch'''''!"
* RockOpera: ''V: The New Mythology Suite'' is about the fall of Atlantis.
* ShoutOut:
** Possible as ''Iconoclast'' appears to have [[TabletopGame/{{Warhammer 40000}} Imperium Dreadnoughts]] [[http://ecx.images-amazon.com/images/I/51LXh+U8+-L.jpg on the back.]]
** The Odyssey quotes the main theme from [[Music/GustavHolst Uranus]].
* StageNames: Russel's nickname could count as he was credited under the nickname for a guest appearance on another band's live album.
* TruckDriversGearChange: For a Metal band, they pull these every now and then. They usually occur in the repetition of the last chorus.
** Examples are: "Through the Looking Glass", "Candlelight Fantasia", "Lady of the Snow", "Paradise Lost" (twice), "The Sacrifice", "Revelation (Divus Pennae ex Tragoedia)" (inverted), "Iconoclast", and "The End of Innocence" (inverted).
** "Set the World on Fire (The Lie of Lies)" seems to do this as well since its last chorus is played half-step higher than the first two; however, the end of the song is played in the same key as the intro and the verses.
* TitleDrop: While it's typical for a song's title to appear in the lyrics, it crops up unexpectedly near the end of ''The Odyssey'' in a manner reminiscent of a TitleDrop.
* XMeetsY: DreamTheater meets BlindGuardian.
