Starcastle was an American progressive rock band from Champaign, Illinois, active primarily during the 1970s. Known for their intricate, symphonic sound, the band was often compared to British prog-rock pioneers Yes, particularly due to lead vocalist Terry Luttrell's similar tone to Jon Anderson. Their most successful release, the 1977 album "Citadel," showcased their blend of complex musical structures and lush harmonies. Despite their short-lived prominence, Starcastle's contributions to progressive rock have secured them a notable place in the genre's history.
