The filmmakers, working with engineer Nick Bergh, have meticulously re-assembled the machine that allowed America to first hear itself. They have replicated the atmosphere of America’s seminal 1920s field recordings down to the smallest detail, with top American artists recording live to disc, using all the original microphones, amplifiers and other equipment from that era. This is the first time that any performer has been able to use this machinery in more than 80 years. Led by Jack White and T Bone Burnett, today’s legends are given a once-in-a-lifetime chance to re-live the experience of the founding mothers and fathers, their idols, and remake the music that changed America and changed the world.
