The fall and rise of Jason Isbell

Jason Isbell's road to his chart-topping new album came with many pitfalls. "Something More Than Free" features songs about the under-privileged people of the rural South, but the roots-rocker also sings about his battle with addiction. Anthony Mason talks to Isbell and his wife, musician Amanda Shires, about his alcohol abuse and newfound sobriety, and their musical collaboration.
