Samantha Hunt, Preservation Hall in Havana, & Walter Martin Plays Live

When Samantha Hunt needed a fictional cult for her new novel, “Mr. Splitfoot,” she invented her own — she even wrote its scripture. Plus, the members of the Preservation Hall Jazz Band make their first-ever trip to Havana, and discover the Cuban connection to New Orleans jazz. And singer-songwriter Walter Martin plays songs from his concept album on a very unlikely subject: art history.
