There is a story that once, after the musicians had played Cage‘s total chance music, as he was bowing to acknowledge the applause there was a noise behind him. He thought it sounded like steam escaping from somewhere, but then to his dismay realized it was the musiaans behind him who were hissing. Often his works have been booed. However, when the audience boo at him they are, if they are modern men, in reality boomg the logical conclusion of their own position as it strikes their ears in music. —Francis Schaeffer, The God Who Is There
