Joshua Mellars has a thing for world travel and world music, and he combines both passions in his latest pair of films. Play Like a Lion: The Legacy of Maestro Ali Akbar Khan is a portrait of the late Indian classical virtuoso and his son Alam Khan, who's carrying on the family musical tradition. Heaven's Mirror: A Portuguese Voyage is about Portuguese Fado music, and features some of the top contemporary fadistas (fado singers), including Katia Guerreiro, Ana Moura, Camané, and Carlos do Carmo. Joshua joined me to discuss the films and the music that inspired them.
