The sound there is good, I'll give you that, and I generally don't drink at shows, either, except maybe one glass of wine but mostly I drink expensive Diet Coke, but the sound at the Vic is still pretty good. That's the problem at the Park West, though; most people end up sitting sideways!
With a band that big, the Park West stage size just ain't gonna cut it and they probably need much larger seating capacity to earn enough to pay all those people in the band.
