Frank Zappa Freak Jazz, Movie Madness and Another Mothers
In August 1969, to the dismay of many fans, Frank Zappa disbanded the original Mothers of Invention. Feeling constrained by the musical abilities of certain members, he cleaned the slate and set about assembling a new group. Hand-picking superior talent from a variety of musical genres, by 1970 the second incarnation of the band was unleashed.
This film focuses on the sophomore Mothers, looking too at the very different projects that book-ended their brief existence; Zappa had incorporated ideas from free jazz and fusion into his music to produce three eccentric albeit influential solo albums. As the new decade dawned and the musical landscape shifted this prolific but often-overlooked period in Frank Zappas career remained a pioneering era for a modern day composer who often confounded both audiences and critics, but who refused to compromise.
Featuring rare footage, archive and exclusive interviews, contributions from many who worked alongside Zappa during this period, rarely seen photographs, and a number of other features which all at once provide for the first documentary film to tackle this phase in the Zappa legend. Includes new interviews with; George Duke, Aynsley Dunbar, Don Preston, Jeff Simmons, Mark Volman, Max Bennett, Sal Marquez, Ian Underwood plus 200 Motels director Tony Palmer, biographers Ben Watson and Billy James and Mojo Magazines Mark Paytress.
