Cello/guitar/electronics duo Janel & Anthony made one of D.C.’s better albums in recent memory: last year’s alluring, largely instrumental Where Is Home. Their follow-up will focus more on vocal works, says cellist Janel Leppin, and some of those pieces will be incorporated into the duo’s early-evening performance at the BioWall. It’s not just another plaza. There’s a 16-by-9-foot video screen and lots of curvy architecture—i.e. a perfectly interesting setting for Janel & Anthony, who show a lot of intuition for how audiences perceive stories within a piece of music.

Sunday: Rule No. 1 of contemporary British theater: Never doubt Alan Bennett. So just trust the conceit of The Lady in the Van, a play adapted from stories Bennett wrote about Miss Shepherd, a vagrant woman who lived in his London driveway. The eccentric lady sits at the center of the action, but the play places just as much emphasis on Bennett. In fact, the script calls for two actors to play him: One narrates while the other interacts with other characters. But Bennett does it to serve the work, not his ego.
