I don't know. To me it's important that it's not really a hologram. It is a projection on a screen. The whole idea of the hologram is that it would be 3-D and could fool you into thinking you are seeing the real person, but this is a flat image on a clear screen. This makes it really limited and I don't think this can replace a live performance. It's more suited for the Michael Jackson show I think because it's a different audience. Tupac sort of worked but it can only be a shock once. Obviously there was some attempt to spring this as a surprise, and everyone knows Tupac said he would be resurrected. I wonder if they could have fooled people if they would have? This would have been a lot more effective when there were good new Tupac songs coming out.Mostly I think this is a novelty that will wear off. The technology will improve and it might be tempting to go see a show and just experience it, but I don't think it could ever feel like a live performance. At a concert you are supposed to feel like you are part of it, participating and affecting the performer with your response. So I think this will work for certain kinds of cult bands where part of the show is being there with an audience that likes what you like, but it's more like a fan club experience. It will also work for audiences that might have also gone to see Michael Jackson On Ice, (though that would not be a good name for it) parents and kids, and eventually there will be a Beatles version but when I think of my favorite bands I don't really want to see them this way.
