Comment How about an entire band of robots? Seriously! (Score 1) 590
There is a band called Captured by Robots, which is made of one human man, and I think eight robots -- who not only play guitar AND bass in one robot (GTRBOT666), but the drums (DRMBOT 0110), horns (the headless hornsmen), and back-up percussion (AUTOMATOM).
The robots play pre-sequenced music, as the man runs around singing and generally being crazy. He also rigged a voice-modifying microphone set-up into his outfit which lets him speak as the various robots, which are all completely automated to move, and even lip-synch.
I had the pleasure to watch this "band" live during their "The Ten Commandments" tour.
They are not as pretty as this guitar playing bot, but I think they are 123% more rad/awes-gnar-some!
