Bono looking through his glasses

"This was an idea that Bono had about two years ago. He heard about this thing called the Sphere being built in Las Vegas and he said I think we should follow the development of this idea because I think it's really new. And what it is is it's a custom built venue. It's not primarily for music. I think it's multipurpose but it has it has a sound system in it so the sound is really good for the band." - Adam on playing U2:UV in Vegas, November 2023
