Revolution Renaissance is a multinational heavy metal band founded by guitarist Timo Tolkki after he left Stratovarius in 2008. The studio lineup for the New Era album was Michael Kiske, Tobias Sammet and Pasi Rantanen on vocals, Pasi Heikkilä on bass, Joonas Puolakka on keyboards, and Mirka Rantanen on drums. Tolkki himself is the only one included in the permanent lineup, which was announced later. In March of 2009, the band released their second album Age of Aquarius with a permanent lineup. The Band said that it was "by far the darkest, heaviest and most symphonic album that Tolkki has ever been involved in." In October of 2009 Timo Tokki announced that both Justin Biggs and Mike Khalilov have left the band due to musical differences. On November 1st, 2009, Blabbermouth.net reported that Magnus Rosén (former bass player for HammerFall) joined Revolution Renaissance.
