Via BoingBoing, here is the readme file:
"For quite some time I've been interested in the idea of allowing you the ability to tinker around with my tracks - to create remixes, experiment, embellish or destroy what's there. I tried a few years ago to do this in shockwave with very limited results. After spending some quality time sitting in hotel rooms on a press tour, it dawned on me that the technology now exists and is already in the hands of some of you. I got to work experimenting and came up with something I think you'll enjoy. What I'm giving you in this file is the actual multi-track audio session for "the hand that feeds" in GarageBand format. This is the entire thing bounced over from the actual Pro Tools session we recorded it into. I imported and converted the tracks into AppleLoop format so the size would be reasonable and the tempo flexible."
The site with the link is more cryptic, "Trent has prepared a file you might find interesting".
