In 1960, composer John Cage went on television to share his latest work. But rather than using traditional instruments, Cage appeared surrounded by household clutter, including a bathtub, ice cubes, a toy fish, a rubber duck, several radios, and performed “Water Walk.” Most people watching had the same question: is this even music? Hanako Sawada explores the boundaries between music and noise. Lesson by Hanako Sawada, directed by Héloïse Dorsan-Rachet.
