Avantasia

Avantasia is a German supergroup metal opera project created by Tobias Sammet, vocalist of the band Edguy. It has been characterized as a rock opera, as it features the contributions of various vocalists and musicians and it consists of concept albums.

Conceived in 1999 as studio-only, two-album project, Avantasia has since released six other studio albums and has toured the world multiple times. It can be divided into four periods of activity. The first, 1999–2002, saw the release of a self-titled single and the full-length albums The Metal Opera and The Metal Opera Part II. The second, 2006–2011, consists of the EPs Lost in Space Part I & II and The Wicked Trilogy, composed of the albums The Scarecrow, The Wicked Symphony and Angel of Babylon. The third, 2013–2016, includes the albums The Mystery of Time and Ghostlights. The fourth period began with the release of the Moonglow album in 2019.
