One of the hottest concert pop stars in Japan is an anime hologram with a vocal synthesizer. Meet Hatsune Miku who appears in live concerts, despite the fact that she does not exist.
She's a vocaloid created with software that anyone can use to create realistic rock performances.
Ms. Miku is not alone. She's done duets with fellow vocaloid hologram Megurine Luka.
Wired Magazine described the technology behind the creation of a wholly digital pop star.
Hatsune Miku is a cultural phenomenon in Japan, yet she lives only in the digital world.
