For years and years I had a jazzy drum'n'bass remix floating around in my head for Aphex Twin's beautiful ambient track Blue Calx.  When I sat down to write it one sleepless night, somehow it lost the jazzy bit. Still, it didn't turn out too shabby, though a bit ravey.  No loops used -- all sequenced from the ground up.  

You can listen to the track right now using the player below, or download the entire mp3 here.
