Salif Keïta, an albino prince from Mali, is a direct descendant of the founder of the Mali Empire, Sundiata Keita. His royal heritage meant that under the Malian caste system, he should never have become a singer, which was deemed to be a griot's role. But since he was cast out by his family and ostracized by the community (albinism is believed to be a sign of bad luck), he was able to pursue his musical passion and became The Golden Voice of Africa.
