The Troy Savings Bank Music Hall is commonly regarded as one of the best acoustic performance venues in the world. Having attended several concerts there, I can confidentially say that it certainly appears to be the case. Sitting in the Orchestra seating, I felt as if I were actually right on stage with the musicians. The sound flows out of the circular stage and reverberates back to the audience.
One of the downsides to the perfect acoustic ability of this place is the fact that they cannot update their seating. I think it's possible that they stumbled onto their acoustic advantage and realized that if they were to change things, they could lose that. As a result, their seats are completely ancient, dating back to what I believe is the turn on the century.
Recent concerts there have strayed from classical music, which is what I have gone there to see. The oldies group America recently performed there, as well as Anousha Sankar, Ravi Sankar's daughter.
