> I'm surprised that there hasn't been more description of what exactly went down during this 'Drive-In' set. Where was the band in relation to the screen? Were they playing to the video in any sense?

The band was playing behind the screen, and at certain points, you could see fractally images of Fishman's drums, Page's keys, and Trey and Mike's fingers/fretboards in the corners of the screen with a bunch of weird trippy space shit in between. I'm not sure if it was a really well done live kaleidoscope effect put on actual video of them playing, or if it was all pre-recorded. (it seemed that way to me but i was on a ton of acid)
