Analysis of information sources in references of the Wikipedia article "Dueto Acosta" in English language version.
The first commercial recordings of vernacular Mexican music were actually made around 1908 by traveling American firms that recorded in Mexico City. These early recordings include selections by Cuarteto Coculense (who turned out to be the first mariachi to record) and Rosales y Robinson. Mexican singers began to record corridos in Mexico City about that time. 'Corrido de Macario', 'Juan Soldado,' and 'El Huérfano,' sung by the duo of Abrego and Picazo, are some examples. Trio González recorded the first corridos in New York, followed by Trio Aguirre del Pino in 1920, and Dueto Acosta in 1923, recording in Los Angeles.
