Great post!
I never was much into John Mayer. But two weeks ago a friend made me see the "Live at the Nokia theater" concert. I loved it!
The concert has multiple settings and band members participate at different time (just as you described). This makes it a concert that shows his diversity as a musician. Interviews are mixed in between the sets. They give a good look on his life and influences.
Strongly recomend it!
