Juan Carlos Cáceres (4 September 1936 – 5 April 2015) was an influential Argentine musician, singer, composer, and lyricist known for his contributions to tango and its related musical forms. Born in Buenos Aires, Cáceres was deeply involved in the existentialist movement and the jazz scene of the city, becoming a prominent figure at the Cueva de Passarato jazz club. Although he studied fine arts, his passion for music led him to become an accomplished jazz trombonist and later a pianist and vocalist.

In the late 1960s, Cáceres moved to Paris, where he expanded his artistic pursuits to include painting, producing, and teaching. He immersed himself in the music of the Río de la Plata region, focusing on tango, milonga, murga, and candombe. His debut album, "Sudacas," was released in 1994, followed by "Tocá Tangó" in 2001, which explored the African roots of tango. His music is characterized by its emotional depth and fusion of various musical elements, including jazz and indigenous sounds.

Cáceres was known for his innovative approach to tango, founding groups such as the traditional París Gotán Trío and the electronic Maquinal Tango. His work earned him the nickname "The Lion" and established Paris as a significant center for tango music outside Argentina. He was a strong advocate for recognizing the African origins of tango, a stance that brought both acclaim and criticism.

Cáceres passed away in Paris at the age of 78 due to cancer, leaving behind a legacy as a pioneering force in the revival and transformation of tango music. His albums, including "Murga Argentina" and "Utopía," continue to be celebrated for their originality and cultural significance.
