best concert venue


What's the best SOUNDING concert venue you've been in? Anywhere in the world. Large or small; famous or obscure?

Speaking of the Iridium Jazz Club (in NYC), Billy Cobham is coming there in September. If you've not seen him, you MUST!
Troy Music Hall - Troy, NY
Academy of Music - Philadelphia, PA (I still like it better than the Kimmel Center)
McCarter Theater - Princeton, NJ (Great folk music venue)
Symphony Hall - Boston, MA (My single all-time favorite)
.
Carnegie and then Concertgebouw (in that order) would be my two favorites.
.
Both provide magical sonics and such a great aura of history.

Sheldon Hall in St. Louis, MO. About 400 capacity and used also as a recording studio as the acoustics are that good.
