Here's some footage of virtual pop idol Hatsune Miku doing a 'live' concert for fans! Miku's singing is generated from technology called VOCALOID by Yahama, where composers can insert lyrics and tune them high and low according to the notes and have the computer sing for you! The concerts use 3D animated characters for projected images onto mesh screens to give the appearance of the character dancing and singing on stage. I personally can't wait for a Sharon Apple concert someday in the future!
