Originally formed in 1984 as Lucifer's Heritage, Blind Guardian adopted their current name during the recordings of their debut album.
Marcus Siepen had a more active role in Blind Guardian's early days, co-writing a good part of the material and contributing as a lead guitarist. He progressively relinquished these roles to Hansi Kürsch and André Olbrich; however, he still shares lead guitar parts live with the latter.
Hansi Kürsch gave up his role as bass player during the pre-production of Nightfall in Middle-Earth, in part due to the increasing complexity of the band's music. Since then, Blind Guardian have hired a series of steady bass players to perform both on tour and in the studio, without being considered official members of the band. Oliver Holzwarth has so far been the longest serving bassist, performing on four albums between 1997 and 2011.
Mi Schüren has been the band's regular touring keyboard player since 1997, though on records keyboard duties are usually split between a variety of musicians.
Thomen Stauch left in 2005, after around 20 years with the band, claiming dissatisfaction with the direction the band had taken on the last two albums he had played on.
Twilight Hall Studios is the band's own studio. It was originally in Krefeld, the band's hometown, but later moved to Grefrath.
