The story of London’s Bombay Bicycle Club is one of constant evolution: since their 2009 debut, the band have woven together elements of everything from wistful indie folk to crystalline math rock. The outfit’s fourth album is a warm, rewarding coalition of these pursuits, offering emotional, synth-driven rock complemented by richly textured samples, big synths, and the dizzying melodies of frontman Jack Steadman. A sampled Bollywood loop introduces the opener, “Overdone,” while the sweeping, R&B-inspired groove of “Home by Now” is anchored by cello and splices of digitally manipulated piano. The hypnotic percussion and eight-bit groove of “Feel” result in the album’s finest track, while “Whenever, Wherever” opens as a pensive ballad before adopting a driving dance beat. A fuzzy kalimba sample and polyrhythmic drumbeat close So Long, See You Tomorrow, finishing an entrancing ride.
