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.
