An interesting exploration of authenticity and cultural appropriation. 

Carter is a wealthy record collector who becomes obsessed with pre-war blues music and a specifically a track the narrator Seth, his best friend and business partner, recorded by accident. 

From there begins a descent into darkness and death, precipitated by the spectral Charlie Shaw and an internet blues fanatic called jumpjim. 

It’s a weird book, but a really interesting one. I listen to the audio version so I’d be interested in reading the hard copy to see how the effect changes.
