I can imagine a ton of logistical constraints. They have U2 doing a residence, and I'd guess that residences are going to be the only options. Designing visuals on such a unique and complex display to match a specific artist is at least a few person-months of effort. You have to plan shows very far in advance and spend a lot of money on show production. This likely excludes anyone but the top-tier performers. And the exterior is basically just a giant ad. It's not a revenue-generator since you don't need tickets to see it.
