Every few years, Des Ark—the musical project of North Carolina’s Aimée Argote—shows up to her local radio station to, as she puts it, “fumble through a bunch of songs, live on-air.” It’s more of an exercise for Argote than anything else—she tests out some new, unrehearsed songs that are later reworked with a full band into a proper album. If you’re a fan of Des Ark—or just interested in the songwriting process—it’s fascinating to hear how a song like “Ties,” from her brooding, dynamic new album Everything Dies, has changed since it appeared on one of those recordings from 2007 (under the name “Covert Conspiracy of Spanish Speaking Cats”). Over the years, Des Ark has deftly surfed the tides of dark, hushed folk and piercingly loud noise-punk. Everything Dies is definitely the former, but live shows often find Argote and her band shredding and thrashing like it’s the last rock show they’ll ever play. At Comet Ping Pong, Des Ark performs with Pygmy Lush, who’s similarly mastered the art of skating between soft folk and guttural hardcore. This show will either find the audience seated and attentive, or moshing and relentless—whichever the case, both versions of both bands are similarly transfixing. Des Ark performs with Pygmy Lush and the City and I at 9 p.m. at Comet Ping Pong, 5037 Connecticut Ave. NW. $12. (202) 364-0404. cometpingpong.com.
