Questlove, the drummer and leader of The Tonight Show's house band The Roots, says he's obsessed with the creative process. His new book, 'somethingtofoodabout', is a collection of his interviews with chefs about how art and creativity apply to their preparation and presentation of food. Speaking with Terry Gross in front of an audience in Philadelphia, he talks about Prince, his late father Lee Andrews, and the food equivalent of the 'Mona Lisa.'
