i love this video. Yeah Hatsune Miku has had concerts basically everywhere except AUS/NZ. Theres definitely nothing wrong with a virtual singer especially when the band is in deed authentic. Who gives a rats ass if shes a hologram, android or cartoon on a big screen the music sounds great either way. In fact a live concert froma vocaloid has many benifits over ordinary singers/bands the obvious one being exaustion. Towards the mid to end of most concerts the bands lose their cool, get hot and the singer huffs and puffs in every second verse. That won't happen with Hatsune. Yeah it might be a little odd for some people but imo its a good step forward.
