Marlon James on violence, politics and the world’s biggest reggae star

The Man Booker prize-winning novel "A brief history of seven killings" takes us from the gang warfare of 1970s Jamaica to the drug-dealing streets of 1980s New York. Its author Marlon James chats to us about how Bob Marley transcended national politics and, in doing so, set himself apart as a controversial figure. He also touches on questions of Caribbean identity and gives us a hot tip on new music from "The Internet".
