Chug-chug-chug-chug-chug; that’s the defining characteristic of “Hung From Wire,” the excellent second song on the latest EP from Atlanta, GA band Small Reactions. The drums lock into place and stay there, the kind of stiff-jointed rhythms that used to power songs by Can and Neu! It’s what’s on top of those rhythms that makes the magic: tight, bright slashes of guitar, a spindizzy bass line and Scotty Hoffman’s clear-eyed, conversational vocals. But for as sharp as the songs edges are, the band is not afraid of chaos. At roughly the midway point, a thick fog of sound swells up, threatening to envelop the song entirely and giving the whole affair a sudden, strange mirage-like sheen. And then, just as soon as it started, it evaporates, and the band emerges standing upright, jaws set, gazes fixed.
