Reissue of a classic. Originally released in 1992 this is a CD with four tracks, each of which carries very quiet, small sounds. Often imitated since, this particular work embodies an original thought; and as such bears the echo and substance of its breakthrough power. Now the idea is out there, that energy is not required. And, historically, the earliest works do tend to retain their aesthetic productivity, since it is in them that a critique is most clearly appreciated and posed. It's also a definitive CD artwork: surface noise would defeat it - and you need a quiet system to listen on.
