Most know Frank Zappa as a psych-rock iconoclast, over-the-top performance artist, and a purveyor of the weird. But those close to him knew him as a perfectionist and a composer, with the single-minded focus of bringing the avant-garde orchestral music in his head to life. Director Alex Winter was granted exclusive rights to use materials from the extensive Zappa family archive, and his new film, "Zappa," is a nearly-two hour exploration of Frank Zappa's life and work, told through largely unreleased material, and narrated mainly by recordings of Frank Zappa himself. Alex Winter joins to talk about the documentary, and its subject.
