Rappers and reality: has hip hop lost touch with its roots?

Hip hop may have started in the Bronx, but today’s rappers are millionaires with business empires that extend way beyond music. Ahead of Jay Z and Kanye West's European tour of their joint album Watch The Throne, Raphael Abraham talks to FT critics Ludovic Hunter-Tilney and Richard Clayton about the evolution and future of rap.

With clips from The Sugarhill Gang, Jay Z and Kanye West, Evidence and DJ Shadow.
