where are the best seats in the balcony?

C2 left front of stage...$35 for Tedeschi Trucks Band Show in November

Personally, any front left or front right balcony seat is wonderful. You get a great view of the stage.

Front row center balcony seats are spectacular

I've sat in the last row in the balcony and had a great view but I'd shoot for the center of the balcony so your view isn't obstructed by speakers/sound equipment.
