Be careful, SweetSurrender. First time, better to try the audio. I've seen fans kicked out twice last tour (in Berkeley and in Jacksonville) for video recording. I know it would break your heart to be kicked out from your first concert. It was Mark himself who pointed at a fan in Berkeley, and it was quite a frown on his face. Someone up high, extreme stage right got some videos, but I'd recommend not taking the chance. Audio you can probably get away with, and people would be very grateful for your audio recording.
