Like other prog-rock acts, the band also issued concept albums on space and sci-fi themes (particularly the 1973 album "Solar Fire" and the singles "Launching Place" off the 1974 "The Good Earth" and "Starbird" off the 1976 "The Roaring Silence") and religious or biblical imagery ("Prayer" on the band's debut album, "Buddah" on "Messin"', Dylan's "Father of Day, Father of Night" and "In the Beginning, Darkness" on "Solar Fire", "The Road to Babylon" and "This Side of Paradise" on "The Roaring Silence" and "Resurrection" on the 1979 "Angel Station").
