It's also the most satisfying.While many of us learned of Iron and Wine by way of Sam Beam's tender and spare rendering of ThePostal Service's "Such Great Heights" on the Garden State soundtrack, those who dug deeperdiscovered a classic American tunesmith with a precocious musical signature.Taken as a whole, The Shepherd's Dog is informed by a sensuality that brings a dreamscape to life.The Shepherd's Dog features guest appearances by Calexico.
