Born in the 1930s in Buenos Aires, Juan Carlos Cáceres became intimately involved with the existentialist movement that thrived in the **** 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.
