Ángel Cabral, born Ángel Amato on October 1, 1911, in the Villa Luro neighborhood of Buenos Aires, Argentina, was a distinguished guitarist, composer, and singer. He passed away on June 4, 1997, in Buenos Aires. Cabral was a quintessential Buenos Aires character, known for his bohemian lifestyle and dedication to music, often performing wherever he was invited without concern for professional recognition.

In the early 1940s, Cabral formed a notable trio with Juan José Riverol and Ángel Robledo, both accomplished guitarists and singers. This group recorded with Sebastián Piana's orchestra, producing the milonga "Jazmín Simón" for the Victor label in 1942. The trio underwent changes over the years, including a brief disbandment and a reformation in 1947 with Alfredo Lucero Palacios replacing Robledo. They also collaborated with the Miguel Caló orchestra, contributing background vocals.

Cabral's career as a composer was prolific, with over 200 songs to his name. Among his most famous works is the Peruvian waltz "Que nadie sepa mi sufrir," co-written with lyricist Enrique Dizeo. This song gained international fame when Edith Piaf recorded a French version titled "La Foule" in 1957. Other notable compositions by Cabral include "Bárbara," "Desagradecida," and "Su nombre era Margot."

Ángel Cabral's contributions to music, particularly in the tango and vals genres, have left a lasting impact, with his works continuing to be celebrated and recorded by artists worldwide.
