Went here to see a George Lopez comedy show. Sat in the upper level, which made it tough to see his hilarious facial expressions, and made me wonder why they could still get away with selling that seat for $70/ticket. BUT, the sound was clear enough and at a perfect volume where we could at least hear him. Some places are either too loud or not loud enough. Not so here. Just perfect. That said, I've never been here for a concert, but I imagine it would be a good venue to go see one, regardless of seating.
The Theatre definitely needs some renovations (ie. Is there a reason they have netting hanging from the ceiling? Are they worried about the crowd getting hit by falling debris?) Cup holders in the seats would also be nice so you don't have to put your drink on the old, yucky floor or have to worry about people spilling on you. Other than being kind of divey, the ticket, drink, and food prices are high, but not surprised considering it's Montclair and considering some of the artists/performers the Theatre hosts.
