On John Cage and 4'33" with composer, educator and new-music journalist Kyle Gann

Colin Marshall talks to musicologist, writer, microtonal composer and educator Kyle Gann, author of No Such Thing as Silence: John Cage’s 4′33″. The former new music critic at the Village Voice, Gann turns his eye and ear in the book to Cage’s most well-known composition, four minutes and 33 seconds in which no notes are played. Famous and infamous in equal measure, 4′33″ has been variously considered a work of genius, a game-changing musical revelation and a charlatan’s publicity stunt.
