The hushed and delicate folk of Sam Beam's Iron & Wine has its roots in some of songwriting's most sensitive souls, like the late Nick Drake and his sparse, magical “Pink Moon.” You can hear the ethereal, fingerpicked softness of Elliott Smith's haunting “Angeles” in Beam's own gossamer arrangements. And the folksy, head-nodding vibes of Simon Joyner's “You Got Under My Skin” are referenced in his easy deliveries.
