Many experts call him the greatest iconoclast of 20th-century music.

The avant-garde composer John Cage is perhaps best known for his pioneering use of silence in music. He also broke ground with the use of everyday objects as instruments, electronics and chance in composition.

He was born in California and died in New York. But some of his most formative years took place in Seattle.
