In reality he gives us his own take on both periods of the blues, sings with a fullness and soul, and tells those blues stories that make it all real. He lived in West Africa for a year and brings some of that in, though more in terms of feel than the obvious riffs and such.
He can do much just with his acoustic and his voice, like the old masters but of course not to duplicate, because that is impossible and ill-advised.
But he gets something of his own out of it. And his guitar playing is very good, too!
I found much to like here. Recommended.
