I completely agree with all the reviews. It was a beautiful day, and the Darien lot is so underrated. If you haven't been there, it's like a huuuuge lawn, wrapped around the actual "lawn," and amphitheater, which sits up on a little hill iconically, and yes the lot is always nicely treated to the soundcheck.
The contrast between Sample and Dinner was one of the coolest ways to start a show I've ever seen or heard. I was under the tent for a change and the energy was 10/10 for the opening, and the rest of the first set. Trey flawed one section of Dinner obviously playing a key flat but it deterred nothing, especially the oooh and aaahs from the crowd. Friend and Possum really rocked. Nice words from Trey on his anniversary, and to acknowledge the passing of Les Paul. Drowned had a thick jam and Rift was nailed. They always seem to enjoy playing there, as Trey says in Live Vol 3 in respect to "this big tent." All in all a great day and night with Phish, enhanced by the weather and venue for sure. 4/5 for me, and try to sit inside there if you can. Much better than the lawn for all reasons.
