Gogol Bordello was a great opening act, and I would actually have liked to have seen more of them and less Ben Harper.
Athough a great guitarist and vocalist Harper lacks stage presence that makes this kind of movie interesting.
DMB was awesome as expected. Wish the whole set was in the movie. Would have happily stayed for 4 hours.
The sound in the movie was fantastic and I'll look forward to more opportunities to see these types of concert films. 3D was excellent at all times, but not the major selling point for me.
