Named after '60s jazz saxophonist Rahsaan Roland Kirk, the openly gay Rahsaan Patterson is probably best known for portraying The Kid on the popular '80s television show Kids Incorporated – starring alongside Fergie, Mario Lopez and pop singer Martika, who gave him his start as a backup singer. But once the child actor grew up, he became a respected if under-the-radar neo-soul singer. Thursday, March 29, at 7:30 p.m. The Birchmere, 3701 Mount Vernon Ave., Alexandria. Tickets are $55.
