Criticizing the band as needing to practice more because they flub a few songs during a tour shows you don't understand how they do their thing. If they flubbed every song of every show, fine. But they've been killing it for a couple years now. A few flubs here and there is part of the price you pay for a band that takes risks and can play at their level and still sound fresh, loose, and inspired. This isn't a Philharmonic concert, it's Phish. Improv genius doesn't come exclusively from practicing; half of it is letting go and letting whatever happens happen. Sometimes that invites flubs. Sometimes those flubs turn into something even greater. You'd rather never get a 8/4/15 Weekapaug because it grew out of a spectacular flub? Brown Phish is the best Phish for my money. Go listen to the albums, they're always played note-for-note.
