Alan Lomax was “the song hunter.” He devoted his life to recording the world’s folk tunes before they would permanently disappear with the rise of the modern music industry. In “Lomax the Songhunter,” filmmaker Rogier Kappers seeks to tell Lomax’s story by interviewing friends such as Pete Seeger, combining it with archival recordings of music greats Woody Guthrie and Leadbelly, and gathering footage of the cotton fields, rock quarries and prisons where Alan Lomax captured America’s quintessential music. Finally, Kappers followed the route that Lomax took so many years ago and traveled around Europe in an old Volkswagen to remote villages in Spain and Italy, hearing memories and music from the farmers, shepherds and weavers whose songs Lomax recorded decades earlier.
