From what I've listened to this year I would strongly disagree (with the nostalgia thing), I think they're kicking ass. On a personal outlook level it's hard to compare something that was once new and exciting to something you've gotten used to over a couple of decades. Plus, the ability to blow away the long-time Phish audience with something they haven't done before gets harder and harder as the years go by and so many things have been done before and others become cliche. I would assume newer fans feel the same way now that older fans did when it was fresh for them. If there was one show I could get to this summer it would be Phish.
