If you've always wanted to be part of a flash mob, head over to Mt. Vernon's Eubie Blake Cultural Center at 6 pm tonight. Dance Baltimore, the local dance organization profiled in our July issue, is organizing flash mob dances for Artscape (July 19 & 20). It's free and open to the public, the song is Pharrell's "Happy," and the steps are easy and can be learned in one session. It's a guaranteed good time. If you can't make it this week, another session will be held next Tuesday at 6 pm. Eubie Blake is located at 847 N. Howard Street, and there's plenty of on-street parking. Call 410-370-8994 for more info.
