So named for the process or looping sounds by running a single reel of tape through two machines, so named by progressive rock guitarist Robert Fripp who was not actually the first to use the technique, but nevertheless contributed heavily to it.

Some other processing was involved in the sounds, using layered and pitch-shifted delays, which results in some cacophonous moments. The track was intended to be in A Minor but the end result kind of went in a different direction.
