Well, don't know if you could pull this off, but it's worth a shot if it means that much to you. You could contact Mgmt, and say you're an A&R agent looking to prospect one of the opening acts, and ask them to will call you a pass for that evening. I did before in the past, and it worked, but I also used to know the go to guy over there when I was in some local bands. The worst they can do is say no. HTH
