I happened tonight to browse the cable TV listing and find on Bravo the "Musical Brain" documentary created by Christina Pochmursky for CTV and featuring Sting, Feist, Wyclef Jean and Daniel Levitin. Levitin is a McGill professor of neuroscience that became a neuroscientist so that he can understand why we do music at all. The documentary is absolutely fascinating, even if a bit light. Levitin also worked recently on a new development, with Bobby McFerrin, called "The Music Instinct" -- that I crave to find and see. He wrote two very well known books on the same topics, "This is your brain on music" being a bestseller. Looking for more information on these, I found "Notes and Neurons", a rather long panel at the the World Science Festival last year. Very interesting topic, very interesting speakers.
