Claudia Heuermann's film, A Bookshelf On Top of the Sky, gives us a rare peek into the working methods of one of the most notorious and reclusive composers on the scene today. Filmed over a ten year period, this documentary includes live footage of Masada, Naked City, Cobra, as well as improvisations, his classical work and rare interviews. A prize winner at European festivals, this film documents Heuermann's very personal, fifteen year odyssey with the music of John Zorn.
