HOLY FUCKING SHIT UNRELEASED COIL REMIXES OF GAVE UP, CLOSER, ERASER, AND THE DOWNWARD SPIRAL.
If the MP3s at Unheard Music don't suit your audiophile tastes, seek yer plunder on the bay and ye shall find FLACs. There's over 40 minutes of music, but the Gave Up remixes should be listened to understanding that they are snapshots recorded during the evolution of the track that would be used in the danceclub scene in Young Americans.
In related news, Danny Hyde is releasing "Moon's Milk in Final Phase" on 180gm vinyl - it's the last thing that he and Peter Christopherson of Coil worked on before Pete's untimely passing. It's a limited run of 500 copies, so get while the getting's good. If you've ever tried to source Coil-related vinyl after it's sold out, you'll be happy to get in on this before it's gone.
