I believe the Art Farmer Mosaic Single "The Time and the Place" was recorded at MoMA, which still puts on jazz concerts to this day during the summer months. I saw Brandon Ross with Roy Haynes' son Graham on trumpet a couple of years ago.
The Philadelphia Museum of Art still puts on jazz concerts YEAR-ROUND. I saw Eric Alexander with Harold Mabern there, and the Maria Schneider Orchestra, and some group called . . . ummmm, let's see . . . what was the name again . . . oh yeah, ORGANISSIMO!
The MoMA concerts are outdoors. You're in the Northeast so you know what weather's like in NY in the Winter.
The Art After 5 (as they're called) shows at the Philly Art Museum are every Friday evening in the museum's Great Stair Hall, so weather generally isn't an issue. If you're ever in Philly and get a chance to attend, it's well worth it:
