IMO it feels MORE three(four!) dimensional than the majority of 1.0 jams. Obviously, there are some outliers, as this isn't the best jam all time or anything, but holy crap this really melds together the best qualities of early 90s & late 90s improv in a way that feels completely fresh. Groove-oriented but not to the point where it just feels like one long vamp, textural ambiance but with a purpose instead of just hanging on the wall looking pretty for the late 90s/2.0 stuff, and running through a bunch of sounds and themes while ping-ponging off of each other and constantly altering what they're doing like the early 90s, but not in a way that sounds contrived with proggish douchebaggery. It's like the eight tentacled amoeba is learning to play speed-jazz.

Either way, in general I don't think they want to be the kind of band that jams that much. Internet loudmouths like us aside, there truly aren't many people going from town to town with this band anymore. They're playing in the moment, and for the most part they're playing the songs that they enjoy playing the most. Now, the outpouring of affection over these shows MAY make them want to up the jam ante a little bit, but do you really think they went backstage after OKC and heard a bunch of shit about how St. Louis was so much better?
Phish will start jamming more if they want to. As much fun as they seemed to be having at Dicks, they looked just as joyful at Superball running through about 700 songs in a day. They've reached a point where the pressure is gone. A point where people just BASK in the jams instead of picking them apart and whining about how they didn't go in the direction they wanted them to. Sitting here in 2012 it seems absolutely fucking ludicrous to bitch about the improv not sounding the way we wanted it to, doesn't it?
I can't blame Phish at all if they want to keep it that way. And I also won't be shocked if they continue to have flare-ups like this, like they've had their whole career, where suddenly they become Gods for a weekend or a week and then return to their earthly bodies.

And christ almighty, what are they playing at the end? I keep thinking of one of the bluesman guest appearances from 97 and I can't place it.
