Champions of retro rockabilly, the Pagan Pompadours emulate the old Sun Records masters with considerable gusto. The Dallas trio favor a raw, taut sound punctuated by the upright slap bass of Blackie Graham and Ralph Wild’s coarse guitar and vocals. Formerly known as the Rockin’ Honky Tonk Fools, the Pompadours open for those fiends from Falls Church, Jumpin’ Jupiter, at 11 p.m. at the 9:30 Club’s Atlantis, 930 F St. NW. $5.
