Sílvio Antônio Narciso de Figueiredo Caldas, known professionally as Sílvio Caldas, was a Brazilian singer and composer who earned the title "The Serenade King." He began his professional career in 1929 at Rádio Ipanema and made his first recordings for the Brunswick label shortly after. Caldas gained further visibility in the theater revue O Brasil do Amor, performing numbers such as "Gente Bamba" and "Malandragem." His significant contributions to the samba and seresta genres include the 1932 release "Maria" and the 1933 composition "Segura Esta Mulher." His partnership with lyricist Orestes Barbosa produced one of the most celebrated songs in Brazilian history, "Chão de Estrelas" (1937). Throughout a career that spanned several decades, he released numerous works, including the studio album Cabelos Brancos (1958) and the 1975 self-titled release, maintaining his influence as a premier interpreter of the Great Brazilian Songbook until his passing in 1998.
