SlyStrat,
I think the secret sauce you miss is the sound of the steam locomotive.
Where I live is the documented birthplace of Boogie Woogie -- the predecessor to most of the Blues. Boogie Woogie came out of the logging camps and the railroads that made large scale logging possible. Although it is easier to hear the sounds of the trains when played on a piano, you can hear Leadbelly play it on his guitar. BTW, Leadbelly lived here when he was a young adult. In fact, he may have done his first jail time here.
The website would not allow me to post a link. There is an excellent example on YouTube. Search for "Leadbelly - The Gallows Pole".
I'd love it if Joe would come to Marshall TX to write his next cd. That would be powerful. He really does better without the extra input from the "professional writers". I think their input created a dilutive effect. Luckily, Joe reconstituted the tunes to a greater strength when he performed them live.
