“We wanted the whole thing to be fully immersive from the moment that people stepped inside,” Trey Anastasio says of Phish’s four-night run at Sphere in Las Vegas on April 18-21. “From start to finish, even in the hallway, you entered an organic world. Then when the lights went down, until the first note of the first song, there was music composed and sculpted for the walk-on, which is not something we normally do. This continued through the set break and all the way out the door. We were trying to get people to lose their complete sense of boundaries.”

As Anastasio looks back on the event, he reflects, “It got better with each passing night. Jon Fishman has been saying over and over again: ‘We’ve got to go back there.’ We all kind of get it now. I can’t wait to play there again.”
