Lorentz worked on the film with composer Virgil Thomson, who shared Lorentz's enthusiasm for folk music and incorporated many folk melodies, along with other popular and religious music, into the soundtrack.
Virgil Thomson compiled a concert suite from his original score, which has been performed and recorded. One of the earliest recordings was for Vanguard Records with Leopold Stokowski conducting the Symphony of the Air; the original stereo LP also included a suite from Thomson's score for another Lorentz documentary, The River.
