Mogwai

These Scottish rockers have been at the forefront of instrumental rock for almost two decades, and somehow their most recent album Rave Tapes sounds like the refined result of all that experience, sludgy distortions notwithstanding. The delicate spiderwebs of guitar and piano are now propelled less by meaty power chords and rumbling floor toms, but rather simply by the fact that as soon as they disappear, you always wish they hadn’t.
