Sego is rhythm distilled and pure. The Los Angeles-by-way-of Provo duo churn out percolating and pummeling beats—looped and loopy, loping and luminescent—that coalesce into persistent, spastic grooves that are just as jittery as they are danceable. The Fringe, their debut mini-album, introduces them as a band turned inside out, the rhythm section taking lead and the guitars and keyboards filling in the space. It's the sound of postmillennial city life created by two millennials from rural Utah.
