Jean-Claude Risset/Lillian Schwartz

Mutations (1969)

French composer Jean-Claude Risset helped to pioneer computer music at Bell Labs in the early 1960s. Made in collaboration with computer pioneer Lillian Schwartz, this film sets animations by Ken Knowlton and others to Risset's titular composition for solo tape, which features a seemingly infinite glissando among its effects.
