I am a casual White Stripes fan at best; I have a few of their albums but I don’t know much about the band and their history and only got into them about two or three years ago. I do know that Jack White recorded some Appalachian folk tunes for the Cold Mountain soundtrack, and I also know that the White Stripes themselves have dabbled in traditional music styles (see songs like “Little Ghost” and “Prickly Thorn, But Sweetly Worn”).
What I want to know is - why was Jack White chosen for Cold Mountain, and, more broadly, what is his relationship with traditional music? Was he sought out because of his position as a famous musician? Did he express interest himself? Did the White Stripes play folk music before Cold Mountain, or did performing on the Cold Mountain soundtrack spur an interest in traditional music?
