With tune titles like "Glasgow Mega-Snake," "Acid Food," and "I Chose Horses," it should be clear Mogwai hasn’t taken any easy, mellowing departures on Mr. Beast. Sure, the album opens with the calming guitar atmospherics of "Auto Rock," but then "Glasgow Mega-Snake" comes bounding out with a crushing jog of a beat and a trademark granite slab of guitars. The Scots also indulge incrementally more beautiful and terrifying dreamscapes, especially the down-turned piano topping that hovers above a guitar storm on "Emergency Trap" and the layers of clear-toned melody that chime over a swirl of choked, feedback-drenched power on "Folk Death 95." There has long been talk of Scottish miserablism, and this colors and grinds the idea blissfully.
