Calema are a duo of two brothers, António and Fradique Mendes Ferreira, from São Tomé and Príncipe who are now based in Portugal. Their name refers to the powerful swell of the ocean along the African coast.
After winning a national music competition back home in 2008, the brothers moved to Portugal to study and build their careers, and they were soon championed by the singer Anselmo Ralph. Blending kizomba, zouk and Afro-pop, their warm, romantic sound has made them one of the most popular acts singing in Portuguese. "A Nossa Vez" became a huge hit, ending 2017 as the most-watched non-Brazilian Portuguese-language music video on YouTube and going on to gather tens of millions of views. Today they are celebrated across the Portuguese-speaking world for their heartfelt love songs.
