Plus shorts with music by Terry Riley. The West Coast looks away from Europe, perhaps accounting for the proliferation of musics drawing on the East for their inspiration. Blackwood's buoyant Musical Outsiders profiles three important composers who don't necessarily reject European classical tradition, but build on it. Harry Partch, of course, was the true renegade of the trio, working with microtonal palettes of daunting breadth. His exploration of diverse tunings, eccentric hand-built instruments, and spoken-word performances, restricted his ultimate acceptance. Yet, his influence can be felt among his peers, Lou Harrison and Terry Riley. Both these composers speak of the confinement of classical systems and instruments. Harrison also speaks of being drawn to the music of China and Japan and then, finally, Indonesian gamelan. Riley reminisces about his apprenticeship with Pandit Pran Nath, the master Indian vocalist. Musical Outsiders is filled with performance: the New Band performing Partch's U.S. Highball, the Abel Steinberg Winant Trio performing several pieces by Harrison, and numerous performances of Riley's work, including one by the Amati Quartet.-Steve Seid (58 mins, 3/4" video, From Blackwood Productions) Followed by: Matrix III (John Whitney, U.S., 1972). In this early computer film, Whitney develops "visual harmonics," combining beautiful multidimensional forms with Terry Riley's equally dynamic score. (10 mins, Color, 16mm, PFA Collection) Music With Balls (Terry Riley, Arlo Acton, U.S., 1969). This historic videotape mixes real-time visual effects, Acton's reflective spheres, and Riley's tape loop-assisted improvisation. Riley's composition melds lyrical repetition with its optical counterpart. (23 mins, 3/4" video, PFA Collection)
