For Rufus Wainwright, music is almost entirely a family affair. The son of singer-songwriters Loudon Wainwright III and Kate McGarrigle, Rufus has been performing unofficially since birth and professionally since 1993. Most of his live shows feature a cover or two of songs and occasional appearances by his other musical relatives, including indie rocker sister Martha and aunts Anna McGarrigle and Sloan Wainwright. Tonight, he’s joined by his other musical sister, Lucy Wainwright Roche, a folk singer, for a few familial duets. But it’s still a Rufus Wainwright show—don’t be surprised if he breaks into a Judy Garland medley at any time.  7 p.m. at 9:30 Club, 815 V St. NW. $40.
