Oh, man, I had my share of concerts at the Pgh Civic Arena back in the day- when you look at the list of people who played that venue, you realize how many more big name acts were touring constantly; pretty accessible. Almost seems like a fantasy now. The acoustics were pretty bad, but The Syria Mosque couldn't hold the bigger crowds (and if memory serves, was not air conditioned). I think I already replied to this thread some time ago, but my first 'rock' concert was there,too, in around '67? Iron Butterfly.
