Thanks to Davin Michael Stedman and Mell Detmer for this one. Mell is just back from Africa. Oumou Sangaré is a Malian superstar and a friend of Mell.
According to her Wikipedia page, Oumou Sangaré was born February 25, 1968 in Bamako, Mali and “is a Grammy Award-winning Malian Wassoulou musician, sometimes referred to as “The Songbird of Wassoulou”. Wassoulou is a historical region south of the Niger River, where the music descends from age-old traditional song, often accompanied by a calabash.”
