National Endowment for the Arts

According to their site, the National Endowment for the Arts strives toward "supporting excellence in the arts, both new and established; bringing the arts to all Americans; and providing leadership in arts education."

The most exciting content on the site for educators is definitely the audio & video section. Listen to Ray Bradbury discuss Farenheit 451; interviews and tributes to opera greats Carlisle Floyd, Richard Gaddes, James Levine, and Leontyne Price; videos of jazz masters Joe Wilder, Candido Camero, Quincy Jones, Gunther Schuller, and Tom McIntosh; and Richard Bausch on how to write.
