Norway's Circus Maximus integrate the new millennium's first wave of progressive heavy metal. Formed in 2000, Circus Maximus consist of experienced musicians Michael Eriksen (vocals, guitar), Mats Haugen (guitar), Espen Storø (keyboards), Glen Cato Møllen (bass), and Truls Haugen (drums), and the group's 2005 debut album, The 1st Chapter, drew comparisons to Dream Theater and Symphony X for its melodic and song-oriented material.
