Produced by DJ Mars and Maurice Garland, The Art Behind The Mixtape attempts to delve into hip-hop's rich history in selling and releasing tapes. The book, which is available for pre-order now, also has a series of online interviews with key players. In this video, DJ Mars sat down with Clark Kent to speak on Kid Capri, Brucie B and how local buzz helped put a price tag on a hot tape. "They were paying $100 for it so no one else could get it,” Kent explains. If you want to see more, check it out above and look out for the book later this year.
