One thing about the Metaverse: I think it will work for some things... not for others. Example: I checked out the Ariana Grande thing on Fortnite... WTF was that ?!?! The whole thing just felt like a video game or some kind of a barbie adventure quest. Is that what people want ?!? Personally, I'm a guy and also happen to be a musician so I want to see Ariana ( the real Ariana, not some 3d Barbie doll ) sing, look sexy in her cute costumes, flirt with the public, interact with the other musicians, dance , talk to the public in japanese , etc. The nice graphics and all that ? Maybe for a music video ( even then, I prefer the real Arianna as we can't make CGI sexy yet ). True that we can't put 2 million people in a concert hall , but we certainly can stream the video concert on PPV ! ( or sell the DVDs ). So I'm not sold in the whole Metaverse thing for concerts, I don't think it works for boybands or boy singers either... most teenage girls want to feel close to their idols, occasionally jump onstage to hug them, and sometimes even get a free backstage pass to hang with them.
It sounds seriously gimmicky and very cringe worthy, I think the only thing enabling this sort of content these days is the fact so many people have medium/high end PC's to cope with graphics and the infrastructure to host it has improved. These virtual worlds have been created in many iterations over the years and it seems very similar to the virtual world called "second life" that probably got furthest along this track years ago. However it is nothing like the physical real world experience, it is all so fake and over hyped, maybe partly because Covid has taken away so many abilities to socialize we're seeing this come to the forefront - but these virtual experiences always end as a flop.
That's the point this is metaverse technology a way to make the audience feel close to their idols and this is a unique strategy developed by fornite. like you said covid changed everything the way to idolize the artist can also go through virtually all technologies have been developed to be shaped to the original and enjoy the audio produced by music. this can be a good step for artists to express their work into the virtual world and have value
