The radio show "World Cafe" with David Dye will focus on New Orleans this week, starting today with a tuba summit at Preservation Hall with Ben Jaffe, Kirk Joseph and Philip Frazier. The week is part the show's "Sense of Place" series, and will feature Trombone Shorty on Tuesday, Ani DiFranco, the Roots of Music and Hurray for the Riff Raff Wednesday, the Treme on Thursday, and Dr. John shows New Orleans' spiritual side on Friday.

Unfortunately, local NPR affiliate WWNO doesn't air "World Cafe," so you'll have to listen online at NPR.org.
