LA’s Corners headlines this Lolipop Records SXSW spillover gig, playing understated riffs with a mischievous vibe. In the video for “Pressure,” the band, impeccably dressed, lays down their brooding outlook. As the music glides on a slippery surf guitar line, a quartet of skaters carve out a long hill and humiliate an innocuous boyfriend in front of his squeeze. Later, when the song’s eponymous refrain kicks in, the boy learns that the crew’s leader has stolen his girl. In a little under four minutes, “Pressure” proves the band’s other man/woman allure, a dark and sumptuous sound. With Psychomagic, Adult Books, The Sloths, The Electric Magpie, Cobalt Cranes, Tele Novella, Kim and the Created, Winter, DJ Proper Yarn. $5, 8pm, 502 Bar, 502 Embassy Oaks, (210) 257-8125.
