Winner of a Grammy Award for the album Talking Timbuktu, on which he played with Ry Cooder and other American luminaries, the legendary African singer and guitarist now invests much of his time, energy and resources in improving agricultural and social conditions in Mali. Film-maker Marc Huraux visited Ali there. Music is an integral part of Ali's life and therefore an integral part of this encounter. Deep, mysterious and utterly compelling, his playing lights up a striking documentary.
