 The soundtrack album is the only public release accredited to The Mystic Knights of the Oingo Boingo, recorded between 1978–79—during which time the band was transitioning into Oingo Boingo.Initial tracks were recorded by the Mystic Knights before their disbanding and completed by members of Oingo Boingo a year later, resulting in the mix of musicians credited on the album.In the liner notes, Danny Elfman writes that "sixty minutes of original music in a dozen different styles needed to be created in and around various older, and often uneven, pre-recorded pieces," and were composed, arranged and recorded in a period of two weeks.
