Believe it or not, the Washington, D.C., area was home to a vibrant country scene that lasted from the late ’40s through the late ’60s, with performers like Roy Clark and Patsy Cline performing regularly throughout the region. Now we’re experiencing a local roots-country resurgence thanks to the efforts of acts like Honky Tonk Confidential and Ruthie and the Wranglers, both of whom are represented on Greetings From the District of Country (Too Many Dogs Music), a brand-new sampler showing that the nation’s capital has again become a country music center. The collection includes everything from honky tonk (the Ornery Brothers) and rockabilly (Dallas Dudley and the Atomic Hillbillies) to Western swing (the Oklahoma Twisters) and the bluesy, twangin’ country-fried rock ‘n’ roll of David Kitchen and the Demolition. Most of those acts (and others on the CD) will be appearing tonight at a special tie-in show. The honky-tonkin’ begins at 8:30 p.m. at Iota, 2832 Wilson Blvd., Arlington. $7. (703) 522-8340.
