The band announced on their official website that on March 23, 2013, they would celebrate the 10th anniversary of Epica in Eindhoven, Netherlands. The concert which would be called Retrospect, would be held in Klokgebouw with a 70-piece orchestra, choirs, international guests and many special effects. The band invited the Hungarian Remenyi Ede Chamber Orchestra and the Choir of Miskolc National Theatre to this show as they were the same orchestra that accompanied Epica in the recording of the live album The Classical Conspiracy.
