For those of you who missed this, Dr Dre and Snoop Dogg headlined at Coachella, and brought on stage with them a special guest... It was Tupac, in holographic form. Anyone high at that point must have been 'tripping balls', as I believe people say nowadays. And anyone not must have thought they were.
But anyway. They did it as a tribute to the late rapper, and are talking about taking it (the hologram) on the road and touring with it, which is a great idea, but also 1. making it 3D and 2. making more. Marvin Gaye and Jimi Hendrix are the 2 Dr Dre has suggested, but realistically it has scope for so much more.
We could 'resurrect' the likes of MJ, members of the Beatles, and in the rock world, Paul Gray, The Rev, Dio, to name but a few. It could be an amazing tribute to the lost legends of music.
But, at the same time, it's not something that should be overused, I don't think. While it would be incredible to witness, I think there is, at the same time, an inherent risk of degrading its value if used too much, to make it have less impact. I'm all for developing this as an idea, but it should be something special every time.
