British designer and artist Es Devlin, who has created touring stage designs for Beyoncé, The Weeknd and Kanye West, among others, was involved in designing visuals for U2's current show.

The screen that envelopes the arena of 20,000 has no borders or dimensions, it becomes both sky and walls, creating a minimal sight line to offer maximum immersion — or subjugation, depending on your point of view.
