Groove Armada’s second album finds the pair expanding on the sonic range of 1998′s Northern Star, spreading out to Franco-electronic pop (“Dusk, You and Me”), big-beat techno (“If Everybody Looked the Same”), and laid-back funk grooves (the masterpiece titled “At the River”). Though it often seems they’re throwing change-ups more to show listeners what they can do, Vertigo achieves the effortless grace of a varied repertoire. – John Bush
