A trailblazer, a muse, a rebel — Jocy de Oliveira changed the sound of Brazil before the world even knew her name. In the early 1960s, she became the first to bring electronic music to the country, already an acclaimed pianist and muse to Igor Stravinsky in his final years. Restless and fearless, Jocy forged her own path through the avant-garde, collaborating with icons from Fernanda Montenegro and Luciano Berio to Karlheinz Stockhausen and John Cage, and redefining what music — and womanhood — could be. When osteoporosis silenced her piano, Jocy reinvented herself once more, turning to experimental opera to explore the power and oppression of the female voice. Now, at nearly 90 years old, she remains fiercely modern — a brilliant, questioning mind caught between artistic eternity and the frailty of the body. As she looks back on a lifetime of defiance and creation, Jocy searches for meaning in the echoes of her past — only to find herself moving, beautifully, in circles.
