Before going global in the '90s, Senegal's Baaba Maal recorded "Sawaly," a standout blend of traditional drumming, horns, and guitar that brims with Dakar street flavor. Maal later made rare forays into both Nigerian Afrobeat, joining drummer Tony Allen for "No Agreement," and the Great American songbook, with his unlikely Pulaar-language take on George Gershwin's "Bess, You Is My Woman Now."
