I have enjoyed a group called Bela Fleck and the Flecktones for some years now. One of the original Flecktones is Victor Wooten who happens to be a really amazing and innovative bass guitar player. I thought I'd share this with you since, surprisingly, I found that it was out on YouTube anyway. He happens to be playing an arrangement of "Amazing Grace" but you don't have to be religious to see the beauty of his playing.
You can hear more of the Flecktones here.
Make sure to listen to "The Sinister Minister" at their myspace site.
