It’s rare that a jazz vocalist has the confidence to allow her band to improvisationally “stretch out” during a set that is supposed to spotlight her singing. But Ronnie Wells has good reason to trust pianist Ron Elliston: The husband-and-wife duo have just released After You—a fine live collection featuring Wells’ world-weary vocals and Elliston’s sympathetic ensemble—on their Jazz Karma label. And no, the duo’s not called the Ronettes. At 10 p.m. at One Step Down, 2517 Pennsylvania Ave. NW. $10. (202) 331-8863. (Christopher Porter)
