In what is surely a terrible omen not only for musicians but also the continued existence of the world as we know it, holographs are now playing sold out concerts in, where else, Japan.

Holographic idol Hatsune Miku is the creation of the group Crypton Future Media, using software from Vocaloid, and the group has put the avatar on tour with a live band. The sight of thousands of screaming fans waving glow sticks while the the holograph "performs" on stage is straight out of a science fiction novel.

The avatar is huge and incredibly realistic.
I'm sure the group that created the Gorillaz wish they had something even close. Look for it at future concerts.
