"Maria Joana" is a 2023 collaboration between Nuno Ribeiro, the duo Calema, and the celebrated fado singer Mariza, released by Warner Music Portugal. The song blends Portuguese fado with African, Latin, and Romani-inspired sounds, telling a story of leaving home and longing that many Portuguese listeners recognize. Mariza is one of the most acclaimed fado voices in the world, while Calema, brothers António and Fradique Mendes Ferreira with roots in São Tomé and Príncipe, are known across the Lusophone world for their warm pop hits. Together with songwriter Nuno Ribeiro they turn the ache of "saudade" into a bright, danceable anthem.
