On the liner notes to Freak Out!, the 1967 debut album by Zappa's original band the Mothers of Invention, Zappa listed some seventy-two names on the liner notes and cited them as influences. The Freak Out List intends to explore who these artists are and what influence they had on Zappa's music. This listing encompasses all sorts of music, from classical composer Edgar Varese to R&B star Johnny "Guitar" Watson to jazzman Eric Dolphy to flamenco guitarist Sabicas. You can hear for instance, how the esoteric classical influence of Varese shaped Zappa's long-form epics like "Lumpy Gravy" or how Dolphy's instrumental prowess led Zappa to incorporate jazz-fusion on albums like Weasels Ripped My Flesh! (1970), which even included a song titled "The Eric Dolphy Memorial Barbecue." Interviews with various Zappa biographers and music historians as well as musicians George Duke, Ian Underwood, and Don Preston, all of whom played in the Mothers at one time or another, help add additional context.

This is a documentary about an unfinished movie. Frank Zappa and the Mothers of Invention try to film the sci-fi epic "Uncle Meat."

A biker gang goes to LA to be part of a biker movie.

"Touring makes you crazy," Frank Zappa says, explaining that the idea for this film came to him while the Mothers of Invention were touring. The story, interspersed with performances by the Mothers and the Royal Symphony Orchestra, is a tale of life on the road. The band members' main concerns are the search for groupies and the desire to get paid.

"Joe Cocker - the Rotating Rocker - and his 42 member communal touring company Mad Dogs & Englishmen with the Master of Space and Time Leon Russell - see them perform in the pleasure palaces of America - it's a moving picture" says the classic film poster. See this spectacular rock 'n' roll tour documentary and get a dramatic visual record that captures the spirit of the hippie era with mind-blowing performances, crazy backstage footage, and spaced-out interviews. Supporting cast includes Claudia Lennear, Rita Coolidge, Sherman Jones reciting "Face on the Barroom Floor," and Canina the dog.
