In 1973, the Who released their rock opera "Quadrophenia," Pete Townshend's semiautobiographical tale of growing up as a mod in 1960s England, and it's been a misunderstood masterpiece ever since -- a fact this documentary aims to rectify. Featuring rare footage of the mod years, vintage performances from the band, and amazing interviews with Townshend and other luminaries of the era, this is the rock doc at its finest.
