I can highly recommend this lecture, Notes and Neurons, from the 2009 World Science Festival.

It also includes some amazing participative musical performances from Bobby McFerrin. http://www.worldsciencefestival.com/video/notes-neurons-full http://www.worldsciencefestival.com/video/notes-neurons-full
