I think this is the version talked about in the book. 7 minutes and 20 seconds long and just a man and his guitar. Also, the book spelled the name of the song wrong at the top of the page; but correctly in the article.
Mali, a landlocked Western African nation is often mentioned when people talk about where the Blues came from. This performer certainly gives some credence to that school of thought. You are either going to love this song and sit in wonder while it plays, or you aren't going to get it. I can't sway you.
