The group was good, whoever did the sound for the auditorium was AWFUL. The bass was turned up as much as possible -- we had to move multiple times to get to a seat where the bass just vibrated it some. Our first set of seats we were vibrating. Even in the back of the theater away from the main speakers the seats were still vibrating.
Every time the bass played, you couldn't hear anything else. So their ballads were decent, but then the bass started and you couldn't hear anything else. Serious, serious failure on the part of the venue and whoever does the sound needs to be fired.
If you do go, you want back of the room, middle. It's got the least bass, so you have half a chance of hearing some of the show. But honestly, don't go unless they fire the sound guy and completely rebalance the whole room.
