On a chilly fall night, Atlanta’s historic Buckhead Theatre hosted an unforgettable, marathon performance by Iron & Wine. The show was a sort of homecoming for frontman Sam Beam, who grew up a few hours from Atlanta, and he delivered a two-hour, 24-song set for the crowd. The eleven-piece band played virtually all of Iron & Wine’s fourth album, Kiss Each Other Clean, plus favorites like “Naked as We Came” and “Boy with a Coin,” before Beam closed the remarkable night with a luminous solo version of “Flightless Bird, American Mouth,” from the Twilight: Breaking Dawn soundtrack.
