Tobias Sammet's Avantasia is a Power Metal "band" from Fulda, Germany, and the solo side-project of Edguy's Tobias Sammet started in 1999. All of Avantasia's albums are Rock Operas and are currently split between two different stories: The Metal Opera and The Wicked Trilogy. Avantasia was named as a portmanteau of Avalon and Fantasia for the world that The Metal Opera takes place in. With some of the guests (including Alice Cooper and Klaus Meine) that appear on the albums, one might come to the conclusion that the project is more or less Sammet's way of showing off his connections if it weren't for the fact that the music is so damn cool. Speaking of guest members, if you can think of a power metal vocalist, there's a very good chance that they've contributed to Avantasia.Compare and contrast Ayreon.Members:
Bittersweet Ending: The Metal Opera and The Wicked Trilogy end with Vandroiy dying, but Anna successfully escaping execution in the former, and the protagonist implied to be committed to an asylum in the latter
Call Back: Many of the lyrics in The Mystery of Time reference an "evil dark tower", which happened to be a villain in The Metal Opera.
Ham-to-Ham Combat: EVERYWHERE. Especially on title track of The Wicked Symphony, which Sammet described in interviews as a three way vocal battle between him, Jorn Lande and Russell Allen, and "Stargazers" from Angel of Babylon, which features those three, plus Michael Kiske.
Hearing Voices: A significant number of the characters in The Wicked Trilogy and The Mystery of Time are imagined by/an aspect of Sammet's corresponding character.
Type Cast: Shamelessly done for both the personalities and the vocal styles the singers are known for. Matos as an Elf Prince, Catley as a wise presence, so on and so forth.
Villainous Breakdown: Falk goes from a pretty ordinary-if-dickish Bailiff into a paranoid, superstitious wreck by the end of The Metal Opera after he is "cursed".
Villain Song: Basically every character who is a bad influence to Tobias Sammet's character in The Wicked Trilogy gets one. Alice Cooper in The Scarecrow, Jon Oliva in Angel of Babylon, Jorn Lande almost everywhere in the trilogy....
Memory, Glory of Rome, and parts of Sign of the Cross and The Seven Angels from The Metal Opera can be seen as these too.
Who Wants to Live Forever?: Death Is Just A Feeling from "Angel of Babylon" plays with this; the implication is that being remembered for your works is worse than dying forgotten, because people will only remember a caricature of your real personality anyway.
