Demons & Wizards was a power metal band conceived as a side-project by Blind Guardian vocalist Hansi Kürsch and Jon Schaffer, the guitarist for Iced Earth. Schaffer wrote the music and Kürsch wrote the lyrics. The band's line-up during the recording of their first album in 1999 featured Mark Prator, who was the drummer on a few Iced Earth albums, and Jim Morris, who has engineered for Iced Earth before, on lead guitar. The personnel for the second album, released in 2005, included Morris on lead guitar and Bobby Jarzombek on drums. The band released a third studio album, III, in 2020, and disbanded in early 2021 following Schaffer's involvement in the 2021 United States Capitol riot.
