Music often provides the soundtrack to our lives, but in "Soundtrack for a Revolution" (UNC-TV, 9 tonight), music was a sustaining force during the civil rights struggle.

Through interviews and archival footage, the 2009 documentary shows how the non-violent protesters used music -- most mined from slavery and the black church -- to say the things they couldn't say, get through the worse moments, and elevate their spirits during the imprisonments, violence and triumphs during the civil rights movement.

Some of the most pivotal songs are re-interpreted by modern acts ranging from North Carolina's Anthony Hamilton to legendary folk singer Richie Havens to Brit soul singer Joss Stone.
