Brooklyn's Parts & Labor takes the atonal screeches and errant atmospherics of experimental music and corrals them into a big, buzzy, open-sky version of glitch-rock. The trio augments its guitar-bass-drums set-up with circuit-bent keyboards and a constant undercurrent of controlled static and thankfully the knob-twiddling never devolves into unfocused wankery. Dan Friel and BJ Warshaw share vocal duties; both men sing with the full-throated conviction of freedom fighters or union-rally singers. The real secret to Parts & Labor is its unrelenting rhythms, though Christopher Weingarten's drums sound almost unnaturally fast, like they've been ProTooled to double their speed. The band's latest, Mapmaker, finds it juggling the terse rhythms of math-rock with fleet-fingered riffage (most notably on "New Crimes") and injecting a brass band in "Fractured Skies" to add a touch of the majesty to the bombast.
