Leather may only have a handful of punishing-yet-complex recordings to their name, but there’s absolutely nothing ephemeral about them and the reputation they’ve crafted. This Philly band’s muscle-bound, crazed-circle-pit-inducing hardcore has been hailed as the heir to the throne left vacant by the Cro-Mags, and they’ve kept themselves uppermost in the minds of hardcore enthusiasts by staying aloof: tantalizingly doling out as few solid hints about their upcoming album as possible without their more frantic fans beating a path to their door. They’re showing up tonight to the sweaty lair in the summertime that is Vox Populi with Raleigh tour-mates Double Negative, who bring with them an unparalleled pedigree (members have played in Erectus Monotone and Polvo), and Long Island’s Brain Slug. With a forecast of high temperatures, savage loudness and apeshit windmilling, this show is going to be painful in all the right ways. Vox Populi, 319 N. 11th St. – 3rd Floor, 8pm, $6 – $8, All Ages – Alyssa Greenberg
