Gryphon's Treasonis the British progressive rock band's fifth studio album, released in 1977 on Harvest Records. Moving further from their early medieval folk influences, the album combines progressive rock, intricate instrumental arrangements and melodic songwriting with elements of jazz and classical music. Featuring tracks including "Spring Song," "Round & Round" and "Flash in the Pantry," it captures the band's adventurous musicianship during the later years of the British progressive rock movement.
