Michael Jackson hologram

[Lex Luthor]

Hello everyone, I’m new here, so for my first topic  I said I do something fun. I was wondering can somebody explain to me the science behind the Michael Jackson hologram used at the billboard awards 2014 for slave to the rhythm, and can somebody explain to me how I can make one of those holograms myself.  I understand scientifically speaking it can be challenging or expensive, but I also understand that in 2018 could be completely possible to make one yourself so if somebody or multiple people can explain to me the Michael Jackson hologram and how I can make a life like hologram of my own that would be great. Thank you, I look forward to your response.

I don't know how they did it, but a common trick is Pepper's Ghost: https://en.wikipedia.org/wiki/Pepper's_ghost

Your first suspicion was a good one.
