The best performance I have ever seen of theirs is actually Roger Waters and Pals doing The Wall live in East Berlin in 1990 - with Bryan Adams, Sinead O'Connor, Cyndi Lauper, and a few other celebs. It's friggin amazing - they build a 550 foot long wall 88' tall during the concert (they had it half finished before the show started).

It's amazing.
