In the mid-1960s, the institution of military dictatorship in Brazil led her to sing increasingly political lyrics. Her show, Opinião, reflected her political beliefs, and she had largely switched to political music by this point. In 1964 she even spoke against bossa nova as a movement, calling it “alienating.” In 1968 she appeared on the album Tropicália: ou Panis et Circenses, performing “Lindonéia.”
She later left Brazil for Paris and in the 1970s abandoned music to focus on her family. She returned to music later, and when she discovered in 1979 that she had an inoperable brain tumor, she increased her productivity as much as possible. She died in 1989.
