From the Academy© Award Nominated director of "Room" and the writers of "Tinker Tailor Soldier Spy" comes an offbeat comedy about a young wannabe musician, Jon (Domhnall Gleeson from Harry Potter and About Time), who finds himself out of his depth when he joins an avant-garde pop band led by the mysterious and enigmatic Frank (Michael Fassbender from X-Men: First Class and Inglorious Basterds), a musical genius who hides himself inside a large fake head, and his terrifying bandmate Clara (Maggie Gyllenhaal from The Dark Knight and TV's The Honourable Woman). Some say this film is dedicated to the late Pink Floyd band member Syd Barett.
