After learning to play guitar at the age of ten, Shawn Colvin was determined to make a life in music—a decision that would send a small-town girl out on the open road for good. In 1997, two decades after she started, she got her big break. Like the troubled would-be arsonist and survivor of her smash hit "Sunny Came Home," Colvin knows a thing or two about heartache—and setting fires. Diamond in the Rough recounts this passionate musician's coming-of-age, from the prairies of South Dakota to the dark smoky bars in Austin, Texas, to the world stage at the Grammys.
