Just before The House of Atreus Act II, the single "Magick Fire Music" was published, with some metal opera outtakes. Inspired by Virgin Steele's metal opera, the German band Tobias Sammet's Avantasia wrote various albums using the same format. David DeFeis appears as special guest on the track: "The Final Sacrifice" included in the Avantasia's second album. After the show at the Bang Your Head!!! festival in 2000 without a bass player, in 2001 Virgin Steele toured with HammerFall and Freedom Call with the new bass player Josh Block.
