The warm, cosy acoustic pop that dominates 21st-century indie rock has its father in Iron & Wine's Sam Beam. Hear his bare bones beauty wafting through Bon Iver's moody, atmospheric folk and The Lumineers' intimate Americana balladry, and catch his lush yet cathartic moments of hushed introspection in Band of Horses' triumphant rock and José González's smooth symphonic melodies.
