He is lost, plain and simple. Suggesting he's "making a deeper musical statement" is kind of a cop out. Right statement, wrong time.
JG was a great musician. It seems like a pretty lame "taste" call to start playing a bunch of out crap in such an inside context. Like good musicians are supposed to do, he plays to the situation...and gets lost.
Admittedly, the first time I listened, I thought maybe he was just trying stuff too. Then I went back and listened and ignored the vibes (something I like to do anyway

). No doubt about it.
No disrespect to Ed Fuqua. Ed, listen again with this in mind and it is SO clear.
I don't care that he's wrong, but I hate couching mistakes in some BS mystique about intention (which is the WRONG word, by the way...it's INTENT). Wrong is wrong, and music isn't random any more than spoken language is. Music's a language, no matter how "out" it gets, and these guys weren't having the same conversation at the same time for a while.
Sometimes cool things happen in those situations. Geoffrey Keezer likes to just play stuff wrong on purpose to see where it leads....but he sure as hell doesn't keep forcing down the throats of a band who isn't responding to it for a chorus and a half. We generally DO respond to it, and it's usually awsome. But skipping 8 bars of the form arbitrarily isn't part of that paradigm.
