The longest-running rockabilly festival in the country, the 21st annual KEXP Rockabilly Ball runs this Thursday through Saturday at the Tractor Tavern. The long lineup of bands includes Slim Sandy, The Royal Deuces, The Black Crabs… and there’s even a car show. More info here.

Here’s the The Mezcal Brothers playing at last year’s ball (courtesy KEXP).

Update: Saturday’s car show won’t be held on Ballard Ave. as previous years, but at the Shanty Tavern on Lake City Way, says Kirsten in comments.
