“Miúcha, The Voice of Bossa Nova” tells the story of the renowned Brazilian singer through her personal letters, audio diaries, home movies, and expressive watercolor drawings animated for the film. The male musicians in Miúcha’s life overshadowed her. She was known as the sister of Chico Buarque, the pupil of Vinicius de Moraes, the second wife of João Gilberto, the musical partner of Antônio Carlos Jobim, and the vocal accompaniment to Stan Getz’s saxophone. But Miúcha’s vibrant spirit couldn’t be held back, even as she struggled to find her own voice in a man’s world.
