evidence: Now, 30 years later, Achtung Baby is once again the centerpiece of a U2 performance, this time not on tour, but for 36 concerts extending into 2024 at the latest rich man's folly, known as the Sphere at the Venetian in Las Vegas. They didn't have to build a television station, but instead reportedly received $10 million from the Sphere's owner, James Dolan, the proprietor of Madison Square Garden and the New York Knicks basketball team, to stage this production, in addition to their $4 million per night fee. The Sphere is a 17,500-person capacity venue housed within a giant orb (366 feet tall and 516 feet wide) located in what's essentially a back corner of Sin City. You can see it all over social media or if you arrive by plane in what seems to be its most frequent incarnation as a giant orange emoji face, smiling and frowning and rolling its enormous eyes. It is, as the advance press made sure to remind us, a venue built for art and not for basketball or the circus or the dog show.
