Ronaldo Leite de Freitas assumed the artistic name Carioca ('from Rio de Janeiro') upon his move to Sao Paulo where he began studying music and conducting. His debut 1980 album, Mistérios Da Amazônia, demonstrates his early mastery of innovative musical forms - blending MPB, psychedelic folk, and even spiritual jazz sensibilities into experimental song structures incorporating instruments like the zither and tabla. Though Carioca may now best be known by collectors around the globe for his piece on Music From Memory's 'Outro Tempo' compilation - his work spans over thirty releases and various other pieces for theater, dance, and film - and Mistérios Da Amazônia is a singular musical journey though Carioca's very first brilliant experimental musical expressions.
