U2 in Cardiff

"When you look up from here you can really see people in the top-tier seats. You can pick out individuals. So it’s not like some of these arenas where you can’t see. The design is very good for communication. And the intimate moments, it’s amazing. Bono can whisper and you can hear it at the top of the venue, which of course is impossible most of the time. We’re still experimenting with that intimacy, and that’s going to be the fun for us over the next few weeks, trying different things." - The Edge on the Sphere shows, September 2023
