Although very small, the Gypsy Tea room has the greatest concerts. Busta Rhymes and Common are some of the artists that have performed there. I waited in a very long line to see Busta Rhymes. But what I liked most was that the Gypsy Tea room had security and police patrol (Dallas Police) to ensure that their patrons were safe. If you drive by, you can find out who will be performing and when because they paint their events on the side wall.
What's funny is that Senator John Edwards will be there this month (April 2006). The Gyspy Tea Room is multi-functional as it welcomes politicans and musicians.
Hope this helps - Enjoy
