Got home from the windy city a few hours ago. About to finish listening to last nights show again. I'm not musically trained so I can't make comments about what chords were used or how the transitions were made but I will say this: I have goose bumps. It is just as good as I remember from being there if not better. I think this one will stand the test of time. Great playing from a great band. I was there all weekend and last night was easily the best of the three. Do yourself a favor and at a minimum listen to Mike's through First Tube.
