This is the first documentary covering Steve Vai's life from 1960 to 1990. (Co-written by Steve Vai.) Cover Vai's life growing up all the way until 1990's Passion and Warfare album.

A montage of the weird, a freak-out film that appeared when the expression was in fashion and in flower, along with the flower people. The film was one of the first exponents of the mobile camera-rock track-optical effect school of filmmaking, and it is much a document as it is a documentary. A repellent and fascinating depiction of the Sunset Strip in Hollywood, along with Haight-Ashbury in San Francisco and the East Village in New York. Tiny Tim amounts to something resembling a recurring motif and narrator.

Let The Music Play is the authorized story of The Doobie Brothers from their beginnings as a biker band in California in 1970, through their breakthrough with Listen To The Music in 1972, sustained success and line-up changes in the mid-seventies and their change of musical direction and further success following the arrival of Michael McDonald in 1976. Worn out by non-stop touring and internal disagreements the band broke up after a farewell concert in 1982. There were sporadic reunions in the eighties before the band reformed permanently in the early nineties and have continued touring and recording ever since. This new film features contributions from all the surviving key band members, their manager Bruce Cohn and long term producer Ted Templeman to tell the full story of the band's highs and lows through four decades of musical evolution.
