To comment on @waxbanks and the most excellent analysis laid out:

Concerning Trey's ever evolving style (which it has and apparently always will be), isn't that what Phish is all about?? Not settling into any one sound or style for very long??? For god's sake they don't even play Mike's Song the same way as they did in the 90s, which is different from the way they originally played it when Mike wrote it!! Trey CAN'T just have one style of playing solos/jams: he's too interested in new things and trying new things out all the time.

This new year's run just continues to show that trend in Trey and the band/organization as a whole. The last time Phish played in the middle of this room, they were on their old tour truck, with hockey stick mic stands and their old instruments. They went as old school as possible. The next time they played in the middle of this room, they again were set up close to each other, but in this "new style" positioning: all four members forming a box, facing each other as a tight, cohesive unit. Then, they are encapsulated in material, playing to each other, for each other, cut off slightly from the outside world. But they brought it into the present, and really to me, the future, with the wildly new light show and the sandwich of brand new songs that highlight and personify themselves as a band right now: No Men In No Man's Land and Blaze On. I'm not saying they were being selfish or keeping themselves apart from the fans. But it was like a move to the future, a major step forward. Phish saying "you've seen and heard us for 30+ years, but we're not the same and never will settle into any kind of pattern, groove, style, sound or appearance you will recognize or be able to predict or count on." These guys set trends only to then move, or blaze, on to something else.
