That was Chris Brokaw. He was very good. I picked up his album "Red Cities" a few weeks after the show, and it’s full of instrumental guitar music. Good stuff. If you don’t mind the complete absence of vocals, I recommend getting it.
Yes, I happened to come across it in one of the Avalanche stores here. You may not be able to find it there now, though, so you might want to try your luck on the Internet.
