In this Imagine, Alan Yentob explores the life and work of the chart topping rapper and multi-millionaire business mogul Jay-Z.

Over a period of six months, Alan follows Jay-Z through key moments in his career, including the media frenzy and build up to his triumphant headline gig at Glastonbury. Jay-Z gives an exclusive insight into his world, with backstage access to his concerts in Los Angeles, Las Vegas and New York, where Alan rubs shoulders with the stars and meets some of Jay-Z's friends including Chris Martin and P.Diddy.

The programme reveals Jay-Z's other passions, which extend well beyond music to modern art, architecture, politics, sports and fashion. Alan also uncovers the source and inspiration of Jay-Z's music, from his misspent youth hustling on the streets of the Marcy Projects in Brooklyn, to his meteoric rise to success; not only has Jay-Z sold an estimated fifty million albums worldwide, but he has also become responsible for a multi-million dollar business empire, and is listed along with his partner Beyonce Knowles as one of the most powerful celebrity couples in the world.

The Simon Bolivar Youth Orchestra of Venezuela, which caused a sensation at last year's Proms, is the product of an extraordinary music education system that has been running for more than 30 years. Children as young as two get intensive music lessons designed to steer them away from the dangers of the street.

With Scotland now trying its own version of the scheme, Alan Yentob investigates the phenomenon and meets its most successful graduate, 27-year-old conductor Gustavo Dudamel, who next year becomes music director of the LA Philharmonic.
