Steve Reich- “Come Out”
This one is straight from the great music archives. In 1966, Steve Reich discovered a curious phenomenon that occurs when the same sound loop is put into a stereo track, with the left track slightly slower than right. After listening for a few minutes, the original sound loop becomes very distant, replaced by a seemingly new sound created by the phasing overlap. Close your eyes and listen to this track with either a good stereo or headphones.
I apologize for the myspace link, its pretty difficult to find a decent .mp3 of this track.
