From her biography at RFImusique.com
She sang songs written by French poets and writers such as Robert Desnos, Raymond Queneau, Jean-Paul Sartre, and Jacques Prévert.
Starred in Jean Cocteau's classic film, Orphée (1950), as well as in films by Jean Renoir, Jean-Pierre Melvile and John Huston.
"In spite of her international star status, Juliette Gréco would remain true to the political ideals of her early days. Indeed, the singer would seize every opportunity to speak out against oppression and use her fame to defend human rights' causes. One of the most famous instances of Gréco's political outspokenness was when the French star performed a concert in Chili while the country was still under the military dictatorship of General Pinochet. Taking to the stage in Santiago to confront an audience made up of soldiers and top-ranking generals, Gréco would launch into a repertoire of openly anti-military songs. The performance proved to be a complete fiasco and Gréco was practically booed off stage - but the singer was immensely proud of her personal act of resistance."
Her voice encompasses millions of poems.
