Both members of the duo, Mariam Doumbia and Amadou Bagayoko are from Mali, but they live in Ivory Cost. Other interestin thing 'bout them, is that they are both blind too.
Now this first track, "Dougou", is awesome. It's a bit more grooving, a bit sharper than the basic pieces of the duo. I think, this is one of their best songs. And it's an achievement!
