Originale, the movie

Here's an interesting document from a moment when the faultlines in the post-war avant-garde were not altogther so clear:  Stockhausen's Originale: Doubletakes, a film by Peter Moore, is a distillation of the New York premiere of Stockhausen's theatre piece, Originale, in the context of the 2nd Annual New York Festival of the Avant Garde.  The core of Originale, here under the stage direction of Allan Kaprow, is the piece Kontakte, performed by James Tenney (piano) and Max Neuhaus (percussion).    In addition, the cast features Charlotte Moorman (cello), Alvin Lucier (conductor),  Jackson MacLow and Dick Higgins (as "actors"), Allen Ginsberg (as "poet"), and — of course — Nam June Paik, reprising the role he created at the work's premier, a part identified in the score by Paik's name.
