The third and final story [of Strangers Below] is a ghost story. It’s about the strange diffusion of the Primitives’ sensibility in modern American roots music. For me, it all started while I was listening to the radio in my Volkswagen. This was in early 2002. I heard the bluegrass legend Ralph Stanley chanting out “O Death,” a chilling a cappella deathbed plea that had become famous as part of the soundtrack to the movie O Brother, Where Art Thou? Hearing that song on country music radio will make the mind turn.
