Calema is a musical duo from São Tomé and Príncipe, formed by twin brothers António and Fradique Mendes, who later established their career in Portugal. They perform primarily within the pop and R&B genres, often blending elements of Afro-pop and acoustic balladry with Portuguese-language lyrics. Active from the early 2010s onward, Calema became known for polished vocal harmonies, melodic guitar arrangements, and emotionally driven songwriting that emphasizes themes of love and personal experience. Their work reflects a crossover sensibility, combining contemporary urban production with melodic structures and rhythms influenced by Lusophone and African musical traditions.
