Watch HDToday. It is an ordinary afternoon for young Mabo Keïta, at home, in Burkina Faso (West Africa). While his parents are taking a nap, he reads a schoolbook on the front porch when a stranger - an elderly man carrying his own hammock - appears for an unexpected visit. It turns out that the old man is a griot, a West African musician/entertainer whose performances include tribal histories and genealogies. The position of a griot is a time-honored one and passed down from father to son for many generations.
