胡安·卡洛斯·卡塞雷斯，Born in the 1930s in Buenos Aires, Juan Carlos Cáceres became intimately involved with the existentialist movement that thrived in the city during the years of his youth. Cáceres was an accomplished jazz trombonist by his mid-twenties, and though he studied fine arts at the university rather than music, he quickly became a fixture in the Buenos Aires jazz community. He became a mainstay at the Cueva de Passarato jazz club, which was not only an important musical venue, but a gathering place for revolutionary and existential thinkers. In the late '60s Caceres relocated to Paris, where he engaged in a wide variety of artistic pursuits, including painting, producing, teaching, and above all, playing.
