Ken Burns explores the true roots of country music in new documentary
Over the past 30 years, the films of Ken Burns have covered the Civil War, the Vietnam War, baseball, jazz and more. His latest project, chronicling the story of country music from the hollers of West Virginia to the fields of California, may be his most emotional. “CBS This Morning: Saturday” co-host Jeff Glor sat down with Burns this week here in New York and one of the film's stars in Nashville to look beyond any current definition of country music and uncover its true roots.
