Another varied program in a weekly series of experimental shorts, this one differs somewhat from its immediate predecessors in its highlighting of a single filmmaker, Peter Kubelka, four of whose films will be shown: Adebar, Schwechater, Arnulf Rainer, and Unsere Afrikareise. On the same program, another smorgasbord: Bruce Baillie’s To Parsifal (1962), Robert Breer’s delightful, animated 69 (1968), Louis Hock’s 1973 Zebra, Robert Fulton’s Path of Cessation and Patrick O’Neal’s Saugus Series (both 1974).
