Phish and U2 performing live at the Sphere in Las Vegas – see what he had to say below.Appearing on SiriusXM’s Phish Radio show recently, Carey spoke of watching U2 perform at the new Las Vegas venue, followed by Phish. Carey, a stranger to Phish until recently, said that he was a “casual” fan of U2, and had gone to their show at the Sphere after being talked into it by a fan. He was admittedly “blown away” at first, before retracting the statement after seeing Phish’s performance.“It blew my mind how great it was,” he said.
