As their name suggests, Pure Ups incline to a sunny sound. Couch surf drums and aquatic bass lines evoke summer’s cold beer and lakeside daydreams. Cooing back-up vocals and shimmer-shatter guitars buoy Hedin’s slacker happy lyrics, which are lazy and urgent by turns, and full of amorous appeal and wistful knowing. But for all the love and longing that glows and shines here, there’s a sense of submerged melancholy, a kind of shadowy undercurrent from which these songs emerge so brightly. The light feels earned by darkness.

Pure Ups release their new EP All Flowing at the Blue Moon Tavern on Thursday, July 2nd. Local favorites and bad-ass brother duo Jesus Rehab, as well as Pitschouse and Chill Spectre round out the bill. Show at 9 pm.
