Squeezing Sorrow from an Ashtray

"We know the air is filled with vibrations we can't hear. We can't consider environment as an object. We know that it's a process While in the case of the astray, we are indeed dealing with an object. It would be extremely interesting to place it in a little anechoic chamber and listen to it through a suitable sound system. Object would become process; we would discover, thanks to a procedure borrowed from science, the meaning of nature through the music of objects." John Cage
