To the person asking about the sound for concerts. I'll be honest, I don't think the concert sound is great and I'm no audiophile. But if you're going for the experience, you should be able to see from most of the upper bowl, but remember it'll be upper bowl and you probably can't see the expressions, you know? The only thing I'd be really wary of is being behind the stage. Usually the stage is set up around 110 111, in front of the zamboni entrance if that helps. You'll want to stay away from 313 to 322 or so or be really sure the sight lines are there.
