San Franciscans Brian and Chris’s dexterous mix of organic instruments with detours into a cyclical, synthetic world is what gives 3 its narcotic tone. The duo also manages to make acoustic guitar seem like a natural match to a parallel, computerized hum. Despite all that, their focus on the organic and their quick shifts between shadowy and bright just add up to the same melancholy melodies that emo and post-rock bands have been kickin’ out for a decade now. All Brian and Chris do is give it a refresher with their drum machine. Too bad that’s not new either.
