Films, Flamboyance and Flash

With the Tribeca Film Festival getting underway today in Manhattan, we get a primer on film snobbery courtesy of David Kamp and Lawrence Levi, authors of "The Film Snob*s Dictionary." They'll explore that intersection between rock snobbery and film snobbery, from "O Brother" mania to Ennio Morricone. Also: Extroverted Chinese pianist Lang Lang is the enfant terrible of the classical world, playing 150 concerts a year, selling truck-loads of CD's, and prompting strong reactions wherever he goes. Today he joins us to perform selections from his latest release, entitled "Memory." He also tells us about his busy extra-musical pursuits that range from a goodwill UNICEF ambassadorship to appearances on Sesame Street.
