Tod Machover of MIT’s Media Lab is devoted to extending musical expression for everyone — from virtuosi to amateurs, and in the most diverse forms — from opera to videogames (Guitar Hero grew out of his group).

At TED2008, he talked about what’s coming next, from new tools for music creativity to the world’s first robotic opera. The video also features an incredible performance by Dan Ellsey, a young man with cerebral palsy who creates and performs music using tools developed in the Media Lab. Ellsey performs his My Eagle Song.
