Here is some fantastic singing and playing of traditional instruments by late Malian griot Fodé Kouyaté (1958-1997). The title of the clip is “An ka wili,” or “Let’s stand up.” It’s an exhortation to work hard for the betterment of your community and your country. It also shows you how much variation there is in Bambara pronunciation and spelling; most dictionaries show “wuli” rather than “wili.”
