More about VOCALOID
Characters: (click to learn more) Hatsune Miku, Kagamine Rin & Len, Megurine Luka, Meiko, and Kaito
VOCALOID software allows users to write their own songs using an entirely computer-generated voice. The popular characters each have a distinct voice, and have inspired all sorts of art as well as music. The charaters became so popular that they even perform "live" concerts where they are projected as holograms on stage. These characters have inspired a worldwide creative community of artists, musicians, animators, and fans to come together and create a fun and exciting experience.
Here's a video of one of the first live Hatsune Miku concerts in 2010 in Tokyo, Japan. This is one of Miku's most poular songs: The World is mine, by Supercell. You can find more VOCALOID music on YouTube at the Hatsune Miku Channel.
