Holy smokes. So I was just looking around at different topics online, and I stumbled across this. Japan has yet again shown it's technological creativity- I can't imagine going to a concert with a holographic performer. The video is definitely worth watching just because it's a rather unbelievable idea. The one thing that popped into my head though was "I wonder how the drummer and guitarist feel about this". It has to be even stranger for them to perform with a holograph.
