All about &

The most recent change in my attitude toward sound has been in relation to loud sustained sounds such as car alarms or burglar alarms, which used to annoy me, but which I now accept and even enjoy. I think the transformation came through a statement of Marcel Duchamp who said that sounds which stay in one location and don’t change can produce a sonorous sculpture, a sound sculpture that lasts in time. Isn’t that beautiful?
John Cage, quoted in Mark Epstein’s Thoughts Without A Thinker
