With the exception of Gorillaz, I probably wouldn't pay to see A holographic artist perform, but I would pay to see a bunch of them perform together. Elvis, Buddy Holly, Tupac, Ricky Valenz, Kurt Cobain, etc. Get DJ BC to create the mashup, and away we go.
I think a Sci-Fi "theater" would be nice too, just imagine all the things from The Matrix happening in real time in front of you (that is, just a believable 3D without glasses).
