As the man who signed Bob Marley and the Wailers, Chris Blackwell is credited with bringing Jamaican music to the masses. He talks to Robert Bound about his upbringing on – and love for – the Caribbean island, as well as the breadth of his musical legacy, which includes playing an instrumental role in the careers of Grace Jones and Nick Drake. Blackwell’s new book, ‘The Islander: My Life in Music and Beyond’, is out now, published by Bonnier.
