Frank Zappa: A Pioneer of the Future of Music: Frank Scheffer's (collage like) documentary on the American composer and rock guitarist Frank Zappa, as broadcast by VPRO in the Netherlands April 22,2007. Most of what’s on here is seen before, particularly in Roelof Kier’s 1971 documentary and/or Scheffer’s own documentary “A present day composer refuses to die”. But there is some new stuff too, particularly interviews with Denny Walley, Haskell Wekler, Elliot Ingber and Bruce Fowler.
