After Joanna's debut in a TV Tupi show, she was invited to sing in nightclubs in Rio. Her first LP, Nascente, was recorded in 1979. Since then, Joanna has recorded almost one album each year. "Nos Bailes da Vida" (Milton Nascimento/Fernando Brant), included in Chama (1981), was written especially for her. Her composition "Decisão" was the theme of the soap opera Brilhante and "Momentos" was that of Coração Alado. Other hits were "Recado (Meu Namorado)" (Renato Teixeira), "Quarto de Hotel," and "Uma Canção de Amor" (Gonzaguinha).

Also very popular in Argentina and Portugal, Joanna recorded more commercial songs in romantic genres like "Amanhã Talvez" and "Amor Bandido" (both by Sullivan/Massadas), dedicating an entire album to bolero in 1998 (Intimidad). ~ Alvaro Neder, All Music Guide
