[20:41] Dio is on tour again. Sort of. The thing is, Dio died in 2010. So now he is on stage as a hologram. This was done already last year, including a bit of interaction with the audience. Way before this, in 2012, a Tupac hologram performed with Snoop Dogg.
And let's not forget Hatsune Miku. I saw recordings of two of her concerts. Really impressive technology.
