Roberto Parra

In September 1957, he arrived for the first time in the Chilean port of San Antonio, where he was hired to sing with the orchestra of the cabaret Luces del Puerto. In the boite Río de Janeiro, he met La Negra Ester, a prostitute and performer of the boite. They started a sentimental relationship that was immortalized in his book Las décimas de la Negra Ester, a poetry book written in décimas. Andrés Pérez Araya, director of the theater company Gran Circo Teatro, later adapted La Negra Ester for the stage; the stage adaptation became a milestone in Chilean theater.

In 1935, when he was fourteen years old, Roberto started to work as a guitar player in several circuses, and cabarets, first in southern Chile. Until the late 1950s, he worked traveling north and south, becoming very popular, along with his brother Eduardo, with whom he formed the Dúo de los Hermanos Parra (Parra Brothers Duet) in 1938. He sporadically worked in several other jobs: on Valparaíso's dry-docks, as a paperboy, shoeshiner, welder, mechanic helper, carpenter, and the owner of a furniture shop, among others.

Roberto Parra Sandoval (June 29, 1921 – April 21, 1995), also known in Spanish as El tío Roberto (Uncle Roberto), was a Chilean singer-songwriter, guitarist and folklorist, member of the Parra family, many of whose members are famous artists. He died in Santiago at age 73.
