The Boro Bar & Grill will hold Borostock, its four-day, free-admission annual festival featuring local rock bands, Aug. 12–15.

Catch a variety of energetic area groups throughout Borostock, including Los Swamp Monsters—performing its own brand of swampcore, a big gumbo where blues, Tex-Mex, south Louisiana music, punk and country come together on a rock ’n’ roll chassis, as the band puts it—performing on Friday the 13th.

The Boro is located at 1211 Greenland Dr.
