The one great stadium experience I had was seeing Billy Joel on his River of Dreams tour. I had seats behind the stage about six rows back. Billy Joel did about half the show with his piano lifted up in place of the drums and Liberty Devitto moved to where the piano had been, so suddenly, most of the people had the behind the stage seats and I was in row six. But other stadium/outdoor amphiteatre shows I’ve been to (Genesis, Peter Gabriel, The Who) have been kind of underwhelming affairs.
