If some artists make “bedroom” music, Kieran Hebden’s is gloriously, unequivocally “outdoors” music. His pastoral Pause was summertime incarnate, hazily ripe and warm “folktronica.” Rounds sees Four Tet again creating beauties that are at once densely swarming and breathtakingly expansive as it sets out for journeys across windy bridges by foot. It’s a far more dynamic album, with chimes and leaves and scraps of static scuttling along the ground, getting swept into tiny, dizzying vortexes. Much of Rounds feels a shift in cycles, a change of seasons in the air. It’s brisk and crisp, with staccato plucks and quivering busyness. In short, it’s absolutely gorgeous.
