Roots Manuva on Ninja Jamm

Roots Manuva is one of the titans of British alternative music and the godfather of British hip hop. We caught up with him in his studio to discuss the adaptation of his iconic tune 'Witness (One Hope)' for the Ninja Tune remix app Ninja Jamm - a app that Freak co-founders developed in association with Matt Black, founder of Ninja Tune.
