Toumani Diabaté [edit: it's actually Mamadou Diabaté] on the kora, a sort of African harp. It's insane, the degree of virtuosity he shows on that thing, not to mention the gorgeous sound coming out of it! I want one! The bassist is Noah Jarrett, son of Keith. He plays appropriately for the context--simply, tastefully, with good tone and intonation...but just listen to that kora player!
