The Library of Congress is having a 2-year series of lectures (08-09, 09-10) relating to new research on music and the brain, and has put up 15-25 minute podcasts previewing each lecture. The topics include music and religion, music and memory, music and crime, to music and language, music and emotion, music and evolution, music and medicine, and more. The speakers include Daniel Levitin, author of This is Your Brain on Music, and his new book, The World in Six Songs (discussed in the podcast), and researchers such as Dr. Patel from UCSD, just to name a few. These podcasts are very interesting, I highly recommend them! Download them to your mp3 and enjoy.
Unfortunately, there don't seem to be any podcasts for the 2009-2010 season.
I wish the full lectures were made readily available. If you find any of those, please share. Thanks!
