I'm hoping to get there, but I'm not 100% yet.
And, yeah, the tickets are pricey, but probably are bunch are sold through subscriptions. It's also in the smaller of the two main halls at the center (several hundred seats versus many hundreds), which has pretty good sound. (The larger hall may sound good for an orchestra, but stinks for an acoustic jazz group.)
I saw Marian McPartland and Dave Brubeck in Verizon Hall, and they sounded pretty good to me! Have you had bad experience with small-group jazz in Verizon Hall, Alan? I agree that the Perelman Theater is the better of the 2 halls for this show--but it still holds a lot of people (about 650 in Perleman vs. 2500 in Verizon).
