Mystery IDM track hidden in Radiohead DVD

This mystery has been nagging me for months, so I'm bringing it to the 
mailing list in hopes one of you recognize it from somewhere.

In 2004, Radiohead released the DVD 'The Most Gigantic Lying Mouth of 
All Time'. Partways through the second episode on that DVD (timestamp 
32:54 overall, in the 'worm buffet' bumper), there is a reversed and 
sped up sample of some IDM track. I don't think anyone from the band 
composed it, it sounds more similar to some tracks by Arovane than 
anything they were putting together around that time. I'm linking the 
sample below, un-reversed and slowed back down, though it may not be the 
right speed.

If anything, I figure it has to be a track from 2003 or earlier. If 
anyone has some leads on what song this is, I would greatly appreciate them.
