Sounds of Silence: John Cage’s 4’33″ Performed by the BBC Symphony Orchestra.
Enjoy:
OpenCulture: The American experimental composer John Cage (1912–1992) composed 4′33,″ a three-movement composition for any instrument, in 1952. It was Cage’s most famous and controversial piece, a four-and-a-half minute reflection on the sound of silence, on the sounds you hear when the music goes silent and the attention shifts to the audience in the concert hall. The cough at the 4:44 mark is deafening.
