If you want specifics, then I have the perfect venue in Calgary, Alberta. I just attended a concert at this hall and it was a fantastic location. Their website says this: The EPCOR CENTRE's Jack Singer concert Hall is described as one of the most beautiful and acoustically acclaimed venues in North America.
Jack Singer Hall - not a huge place, but very cool!!
It has this cool feature, as described on the webpage: Suspended high above the stage is an 185,000-pound (90-ton) laminated sprucewood acoustical canopy that can be raised or lowered to tune the hall according to the specific needs of each performer.
If David does come to Calgary, I hope I have as good of seats as I had for the last concert there--front row, centre!!
