The Importance of Being Open-Minded

I thought the fall tour, and especially the two San Francisco shows around New Year's, was for me like the first time I got on stage what I was going for in my head. And then I was back to playing like I didn't want to play last night. So that's why... What about putting a wall behind you? It would blow the wall down. Maybe some Tyvek that's perforated or something. Can they do something? Maybe a Gore-Tex on the stage? Can they just have to figure out how to play through it?
