Watch Bombuj. John Jacob Niles is a portrait of the adding machine repairman who came to Eastern Kentucky in 1909, “heard the songs [his] father sang,” and became a much-noted “arranger, expander, collector, recorder, and performer” of traditional Appalachian ballads. Niles played an important part in the national “discovery” of Appalachian folk music. He describes how he travelled with the photographer Doris Ulmann through the 1920s and 30s — she taking pictures of the people, and he learning their songs. The film shows Niles in concert, at home, at work arranging his music, and explaining the historical place of balladry in American music.
