Neil MacGregor's history of the world as told through things that time has left behind. Throughout this week, he is examining the often troubled relationship between Europe and the rest of the world during the 18th century. Today he tells the extraordinary story of a now fragile African drum. It was taken to America during the years of the slave trade and where it came into contact with Native Americans. The drum was brought to England by Sir Hans Sloane, whose collection became the British Museum in 1753. This drum, the earliest African-American object in the Museum, is a rare surviving example of an instrument whose music was to profoundly influence American culture - bought to America on a slave ship and transported to Britain by a slave owner. The historian Anthony Appiah and the writer Bonnie Greer consider the impact of this drum.Producer: Anthony Denselow Music research specifically for the Akan drum: Michael Doran
