Without leader Natalie Maines, the Dixie Chicks might sound a lot like Sheryl Crow. At least that's the impression left by the music of the duo Court Yard Hounds, featuring Emily Robison and Martie Maquire, the two sisters of the Chicks trio. Together, these country-rocking siblings create a familiar blend of folk, bluegrass, country and pop/rock. The resulting stew is missing Maines's feistiness and coarseness, but it still packs a punch. The band's self-titled debut from last year even included a blistering gem about a son's struggle to come out as gay to his father, "Ain't No Son." Virginia native Justin Jones opens, playing his dark, country-tinged rock. Thursday, May 12. Doors at 7 p.m. Sixth & I Historic Synagogue. 600 I St. NW. Tickets are $40.
