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. At DC9, Polyon shares billing with Solids, a two-piece punk band from Montreal. Like Japandroids and No Age, Solids create a massive sound with minimal instrumentation. The band’s 2014 record Blame Confusion is all about build-up: After a shimmer of guitars and rapid-fire drum fills, the album is essentially a 40-minute release of punk fury. DC9 is all about intimacy, but these bands perform like they should fill arenas. Polyon performs with Solids and Stronger Sex at 8:30 p.m. at DC9, 1940 9th St. NW. $8. (202) 483-5000. dcnine.com.
