The Coil song of this title was 90% done by band member Thighpaulsandra. The 12 minute and 40 second piece was mostly created with a Roland SH101, a Fenix (some type of modular synth) and overdubs of Coil member John Balance's voice. This soundtrackesque song begins with a quiet rhythmic series of electronic beeps and other little noises, eventually becoming a fast-paced mesh of the beeps and other strange, eletronically manipulated sound. Those overdubs of Balance's voice are the only vocals, which aren't discernable. What he's saying is anyone's guess, though Coil probably knows (having created the song and all).
As evidenced by the title of the album this song is on (Musick To Play In The Dark, volume one), this song sounds much more übercool in the dark.
