France-via-Ivory-Coast musician Fatoumata Diawara has one of those voices that envelops you in its warmth, its smoothness, its vibrancy whether you speak her language or not. Her music combines jazz, folk, and Wassoulou (think West African blues) into a sumptuous whole, as her compositions spiral through full-throated solos and surprisingly funky, bass-laden breakdowns. The disparate cultural influences informing her sound seem to actually warrant the old “world music” tag, and at the center of it all is that voice, the sun at the center of her songs.
