Hope someone knows - I'm a huge fan of the music and not finding this anywhere. Who was the session guitar player doing a lot of the "country" stuff? Not Buddy Miller, but the other guy, kinda beefy with the black beard. Whenever they showed close ups of somebody's hands on a guitar, it was him. Looks easy until you try to do it. So who does Buddy Miller pick to play guitar with him on stage?
