Go inside one of the greatest-ever untold stories: how the ordinary people of America were given the opportunity to make records for the first time. The Big Bang: At the height of the Roaring Twenties, music scouts armed with cutting-edge recording technology set out across America to capture the unsung voices of everyday folk. This is the Big Bang of modern popular music–the first time America hears itself. Blood & Soil: America's poor–cotton field slaves, mine workers, sharecroppers–find freedom through music, creating gospel, protest songs, and Delta Blues. Out of the Many, the One: Exotic cultures spanning America are captured on record for the first time–inventing new instruments and new cultural identities as disparate voices harmonize in a musical melting pot. The American Epic Sessions: Jack White and T Bone Burnett produce an epic recording session using the only working 1920s recording device in existence in this tribute to the artists celebrated in the documentary.
