Many important decisions are made after a late night binge of tacos and beer. I can attest to this, as there’s something in those delicious carne asada burritos that opens a flood of information to your senses besides long showers and sleep. Recent artist of the month poll winners Arms that Work claim to have written most of their debut release, “Totalitarian Gov.” in the midst of these sessions. And it certainly shows, as the EP flourishes with bustling creativity – the trio’s brainy, serpentine arrangements are constantly in flux, anchored with frenetic guitar passages that mingle with warbling synth tones and contrasting dynamics. It actually reads more complicated than it sounds; after all, their arty, instrumental interplay flexes the time-signature kinetics of math rock. But Arms that Work like to shift gears fluidly, offering a more streamlined form of guitar rock that mirrors Superchunk at their most impassioned.
