NYC: catch a show at the Beacon Theater, my favorite NYC venue, or at any of the bazzillion concert places. Rockwood Music Hall has something going on every night. Venerable Jazz places: the Iridium, Blue Note, B.B. Kings, Birdland, etc etc. Great guitar shops : Matt Umanov's in Greenwich Village -- Rudy's Music -- 2 locations. The Lincoln Center venues for opera, symphony, and ballet. And don't forget the Metropolitan Museum has a great collection of musical instruments
