It sounds like in the video, Frederic Sanchez mixed The Fall's "Copped It" with Stravinsky's "Firebird Suite." (Tough to hear, but you can catch it at the very beginning and around 4:10) Gorgeous addition to the soundtrack.
Pre-show, an ambient remix of The Firebird Suite was being played. I don't remember hearing the Firebird mixed in with "Copped It", but it was loud and it was a short show. I could have missed it. I don't think it's in the soundtrack, however, on fredericsanchez.com. Not sure which one is correct, but I like it mixed with the Stravinsky, either way.
