In the 1990s, Boston’s Swirlies pushed the limits of what could be abrasive and poppy at the same time. That’s kind of Psychedelic Horseshit’s thing now, which might explain why these fairly different bands are touring together. Over five albums, Swirlies blended weirdly tuned atmospheric heaviness, Pastels-esque boy-girl vox, and unidentifiable skronk, landing on what was basically shoegaze for destructive librarians. Psychedelic Horseshit is more forest-bound and less cute, but for the most part just as damaged-sounding. Sometimes the Columbus, Ohio, group is labeled “shitgaze,” but that doesn’t quite work: The guitars tend to be inebriated and wiry; if anything’s colossal in Psychedelic Horseshit’s songs, it’s a busted synthesizer. But those are minor details. The point is your parents will hate both bands.

Swirlies perform with Psychedelic Horeshit and Wild Fruit at 9 p.m. at Rock & Roll Hotel, 1353 H St. NE. $12.
