Now, from Olympic legacies to Hollywood legacies, we want to take a moment to pay tribute to a pioneer actor and director, Al Freeman, Jr. Freeman is perhaps best known for his portrayal of Nation of Islam leader, Elijah Muhammad in Spike Lee's 1992 epic film "Malcolm X." Freeman's performance won him an NAACP Image Award for Outstanding Lead Actor in a Motion Picture.

JACKI LYDEN, HOST:

For many years here at NPR, Gwen Thompkins was an editor and then went to East Africa as a correspondent. She's always had a great ear, so perhaps it's not surprising that her brand-new music radio show called "Music Inside Out with Gwen Thompkins" listens to music in a revealing way. The show is from Gwen's hometown, New Orleans, and every week she talks to people in Louisiana who have devoted their lives to music - songwriters, musicians, producers, you name it.

Gwen Thompkins joins us now from WWNO in New Orleans. Congratulations.
