As far as I know, you can't buy it. It's a good audience recording that surfaced at dime only just last year.
6/13/01 World Trade Center, NYC Symphony No. 13 for 100 Guitars Hallucination City
Wharton Tiers plays some incredible drums...for an hour straight.
It was later performed in a few cities in 2001 as far as I know. I keep waiting for a soundboard or possibly a studio-recorded release, but I'm not so sure it will happen, at least from the 2001 era. Branca and his guitarists performed the piece again this year a few times. Here's a clip (at nine minutes, the longest one) from the Roundhouse show in London.

On that landing page there are links to several other shorter clips of the same show from different cams. There's also a snippet from Dublin.
I completely agree with some of your critiques though.
For instance, I'm right there with you concerning Blonde Redhead.
