A smaller ensemble of the orchestra accompanied Doro and her usual touring musicians on tour, but the full orchestra was on stage in August 2004 at Wacken Open Air for a strictly acoustic set, an unusual performance for the largest European heavy metal festival.  Special guests of the night were former-Iron Maiden singer Blaze Bayley and guitarist Chris Caffery (Savatage, Trans-Siberian Orchestra).
