Op Maayo Men ("Our River") is a meeting place for the Peulh of Senegal and Mauritania as well as a symbol of peace and fertility. Malick Pathé Sow sings about historical figures and events, the protection of minority language, and he calls for coexistence in diversity, the environment and nature. These themes are relevant not only in the country of their origin but also in the musicians' current environment, which is Matonge, the black district of Brussels.
