We begin today's Midday on the Arts program with the legendary jazz impresario and NEA Jazz Master, Todd Barkan. With Chef Robert Weidmaier, he is the proprietor of the Keystone Korner nightclub in Harbor East, at the corner of Eden and Lancaster. Tonight, tomorrow and Sunday: the great Vibraphone virtuoso Warren Wolf appears with the Wolfpack. And next weekend, Christian McBride, the host of NPR’s Jazz Night in America will be there with his band, the New Jawn. Keystone has music every night of the week, too, and Sundays, they offer a brunch. This month, for at least the next three Sundays, members of the Baltimore Symphony Orchestra will perform chamber music from 11-2. BSO players are in the 12th week of a lockout stemming from a contract dispute with BSO management, so if you’ve missed them at the Meyerhoff this summer, you can catch small groups of them at Keystone Korner on Sundays. Check the links above for a complete listing of all the acts appearing at Keystone.This program was livestreamed on WYPR's Facebook Page, and you can watch the video here, beginning at 0:00 and running through 20:30.
