Following “Lovers’ Revolution” and an unplugged take on “Caught in the Briars” comes another track suggesting the new Iron & Wine record will deliver: “Grace for Saints and Ramblers.” Gone is the loose-knit rhythm section from the first single; Sam Beam & Co. chase an insistent pace this round with brass flourishes, handclaps and jazz-infused harmony vocals breezing through the upbeat cut. They even hint on a Fleetwood Mac vibe a few times. Spin the latest taste of April’s Ghost on Ghost above.
