If there's no cameras then there's got to be a reason for this. I know MAv mentioned bringing his own crew to film the show. I'd be pretty happy if this show was realeased to the fans professionally and I'm sure there would be tons of people willing to pay for such a thing.

What about recording audio? Is this allowed tonight?

I haven't heard anything about audio either.
My first impression when I heard no video is that they might drop a new track that they don't want out to the public yet. That would be well worth not having a video of the show for me!
