Youssou N'Dour is a Senegalese singer. He helped develop popular music in Senegal, known in the Wolof language as mbalax, a blend of the country's traditional griot percussion and praise-singing with the Afro-Cuban arrangements and flavors which made the return trip from the Caribbean to West Africa in the 1940s, 50s, and 60s and have flourished in West Africa ever since.
