Hypothetical - Live concert in game

Just popped into my head when I was watching some Youtube videos of latest Smashing Pumpkins concert in Chicago. What if Square Enix hosted live concerts in an instanced area that could be streamed to however many instances any given data center would need? I am not sure, but I doubt this has ever been done in an MMO that I am aware of. I mean the raves/bard concerts thing is already pretty popular in game, and the influx of new layers has likely netted them some tidy increase in profits to pay (insert musician/band name) to play. Players would just log in and join the concert with a few thousand others.

Just idle thoughts, curious about what others would think

I think they may have done that already in fortnite. Still a neat idea though.

AQ games have done concert events before with real bands, so it's not totally unrealistic.
