Nicholas Hush, 1960s record producer, has a vision for the future of pop music. After a series of prophetic dreams he wants to combine occult imagery with upcoming trends to create a new, groundbreaking look. His secretary, Valerie Chill, is tasked with finding consultants and funding while he crafts the perfect album. Quickly their project becomes entangled in other, larger machinations, and two teenage pop acts become responsible for international intrigue, brainwashing, and an occult massacre. Taking inspiration from the lives of Joe Meek, Phil Spector, and Timothy Leary, BACKMASK is a speculative look at how hidden messages got into pop music.
