The story of the American civil rights movement told through the freedom songs protesters sang on picket lines, in mass meetings, in paddy wagons and in jail cells as they fought for justice and equality. The music enabled African-Americans to sing words they could not say and helped protesters face brutal aggression with dignity. With heart-wrenching interviews, dramatic images and contemporary performances by top artists, including John Legend, Joss Stone, Wyclef Jean and The Roots.
