Just received an email that Dan Levitin, author of the excellent This Is Your Brain On Music, is having an online book event today at 5pm California time for the paperback release of his latest book, The World In Six Songs. I'll be at the office so don't know if I'll be able to check it out, so if you do let me know how you liked the format:  http://www.ustream.tv/channel/daniel-levitin
