Volume control is an essential element of any rock show, but its value is often underrated. Most bands stick to a tasteful level, leaving eardrums and some conversations intact. D.C.’s Polyon does not operate that way. The band’s dialed-up sound may seem excessive, earth-shattering even, but that’s part of its appeal. Whenever Polyon plays, fuzzed-out guitar and cymbal crashes reverberate past the point of good taste until the hooks clang away in your guts. The band’s that good.

EAT THIS

Dacha Beer Garden is back for the season, and this time, it has real toilets. The Shaw spot is in the process of expanding into the former Chinese carryout restaurant next door. Come April, a first-floor market and cafe will be complete, along with a kitchen that allows the beer garden to serve a full menu with schnitzel and smorgasbords of meats and pickles. In the meantime, you’ll find plenty of beers on tap, plus ciders, meads, and wines. And the disappearance of porta-potties means 30 percent more seating. Read more on Young & Hungry.
