It's hard to overstate the impact that John Cage had on music. Not just classical music either, but across the board: from the seething orchestrations of The Beatles' "Day in the Life" to the indie experimentalia of Stereolab, the squalling guitars of Sonic Youth and the skittering drums and tonal arrhythmia of so much contemporary electronica. There's not much over the last half a century that hasn't felt his touch in some way.

Cage would have turned 100 today. Rather than taking a minute to remember the man, perhaps take four minutes and 33 seconds to just hear the sounds of the space around you. He probably would have liked that.
