We have really reached the technological point in society where stars need to put their wished into their Wills, and might be nice to have laws so relatives can't overturn whatever they decide. That said, with just a few more advances in Holo technology, I'm all for it IF the person was OK with it, and IF it is done correctly!!! I'd much rather go see a legit Elvis concert than autotuned junk.

And via restored, high quality video, Elvis has played to many who weren't alive to see him even now. And there are no Queen shows without a few HD performances from the Legend Freddie Mercury. Decades after his death and he still holds stadium crowds in the palm of his hands!
