“6 and 12 string guitar” by Leo Kottke was a favorite of a few of my friends in college where I first heard it. I didn’t think anyone could play guitar like this. It sounded so massive. However in one sense I was right, he had to change his style significantly due to RSI brought on by the aggressive way of playing he had taught himself. I’ve kept up with him over the years.
If you get a chance to see him in concert, take it. If he’s on his game, it’s worth it.
I even like his singing voice.
