More Conversations About Music and Brains
David Byrne and Daniel Levitin discussing the various ways music affects the brain...both chemically and theoretically. It's more a conversation than an interview, and it's truly fascinating stuff.
Set aside about 10 minutes and give it a read. It's amazing that music has been an important part of human life for thousands of years but only recently is anyone working through real science to discover why it's such an important part of life.
There's also a link on that page to watch the entire conversation. I haven't done that. But it's there if you so choose.
