When he first set foot on the African continent about 15 years ago, J.B. Moundélé was still Jean-Baptiste Dobiecki, a French jazz saxophonist introduced to African rhythms by a few heavyweights of the Parisian scene. The effect of his stay on African soil, on the occasion of a concert given in his country by the Cameroon vocalist Gino Sitson, can be described in a single word: a "revelation," to which the musician refers through the title of his new album.
