I really didn't know either.
I found some of both on the Internet. You can find almost everything on the Internet. Googling
site:blogspot.com artistis a wonder.
Then I put it all on my Creative Zen Stone. No LCD. So I had to guess.
Rory's self-titled album. One Joe song. I could tell the Joe because it shared a stone and style with Sonny Landreth. "So, It's Like That". Like Sonny without a slide.
Rory was good, really good. But I'm not seeing great.
So, for Joe vs. Rory, I say Richard Thompson.
