John Cage
A major figure of 20th century avant-garde music, John Cage produced experimental works, invented the prepared piano, introduced silence as a compositional element, developed the ideas of chance and indeterminacy, and made use of electronic devices.
In the late 1960s, Cage widened his practice to the field of the plastic arts. His first work, Not Wanting To Say Anything About Marcel (1969), paid homage to his friend Marcel Duchamp, who had died the previous year, and marked the start of a highly productive period of pieces ranging from graphic art and poetry to installations and sound sculptures
