With unfettered access to the Zappa Trust and all archival footage, ZAPPA explores the private life behind the gargantuan musical career that never flinched from the political turmoil of its time. Alex Winter's cast list features Frank's widow Gail Zappa and several of Frank's musical collaborators, including Mike Keneally, Ian Underwood, Steve Vai, Pamela Des Barres, Bunk Gardner, David Harrington, Scott Thunes, Ruth Underwood, Ray White and others. The soundtrack is a perfect complement to the film, available as a 5-LP 180-gram vinyl set for the Zappa completist. With 69 songs in total, there are 12 previously unreleased recordings from the Zappa archive along with his 1978 appearance on Saturday Night Live; 24 more Zappa songs from his extensive catalog spanning four decades; songs from Zappa's labels Straight / Bizarre Records such as "No Longer Umpire" by Alice Cooper and "The Captain's Fat Theresa Shoes" by The GTO's; 2 classical compositions by Edgard Varese and Igor Stravinsky, and 26 original compositions newly composed by John Frizzell for the documentary - all giving the universe a sonic exploration of Frank Zappa's musical brilliance.
