Ha. Nice little map.
I vary based on the type of show I go to. If I'm going to a jazz/blues gig, I'm usually sitting at a table or the bar, enjoying an appetizer and taking in the ambience. At a metal show I'd be the frontline warrior. Of course, at most metal shows that I would go to, everyone is a frontline warrior until a moshpit breaks out. If I'm seeing a band specifically and for no other purpose than to watch them play, I'm content standing about anywhere I can see them.
I tend to go to jazz/blues gigs the most. Especially if I know the band.
