In this week's episode, Laurie meets Jo Haynes, the author of a new study which considers the significance of race to the understanding of music genres and preferences. What does the 'love of difference' via music contribute to contemporary perspectives on racism? The research draws on interviews with people from the British world music scene. They're joined by Professor Paul Gilroy.

Laurie also talks to Daniel Stedman Jones, the author of a new book which traces the origins of neo liberal economics.
