evidence: Fast forward a decade, to September 2023. U2 has taken up residence in Las Vegas’ newly unveiled crown jewel, the Sphere. The $2.3 billion venue is a pet project of James Dolan, the polarizing businessman whose empire also includes Madison Square Garden and the New York Knicks. It boasts around 18,000 seats and 160,000 speakers, and the pièce de résistance is a gigantic wraparound LED screen that encompasses the entire exterior, walls and ceiling. Its 268,435,456 pixels can transform the arena into a desertscape, outer space, anything that the imagination and visual technology can conjure, in 256 million dazzling colors. Its scale and ambition are extraordinary, unlike anything yet seen in live entertainment (though plans are already underway for a replica in east London). Early reviews are glittering. I hated it.
