Far be it for me to tell anyone what to do but if I was to I’d suggest you read Janet Maslin on John Szwed on Alan Lomax.
I, much like you, am a huge Lomax fan and don’t know where we would be without his and his dads running around the country, recording, legendary folk singers and releasing it.
Janet Maslin, a superb writer, writing about John Szwed (who was mentored by Lomaz) writing about Lomax is just amazing.
