e was born in Buenos Aires in the neighborhood of Almagro. Many aspects of the life and show business career of his brother Pedro were known, instead very little has been found about Juan.

He was an employee in the Buenos Aires Customs office and, at the same time, he used to sing with his friends just for pleasure and with no great expectations. However, some tango researchers have pointed out that he carried out an almost professional task when he was summoned to appear with the aggregation led by Alfredo De Franco for a few stints. Later the same happened when he joined the ephimeral orchestra fronted by Cátulo Castillo.

Surely it was because of his brother, then refrain singer (estribillista) in the Julio De Caro’s aggregation that they managed to sing, teaming up as a duo and in French, the tango “Dónde estás corazón” which was recorded in 1930 for the Brunswick label.

The most outstanding stage of his music career was between January 1930 and June 1931 when he recorded refrains for the Juan Bautista Guido Orchestra which from March 1927 used to frequently visit the Victor company studios.

The initial lineup included the following names: Guido and Domingo Platerotti (bandoneons); Elvino Vardaro, Alcides Palavecino and Eugenio Menjoulou (violins); Pedro Vergez (piano) and Alfredo Corleto (double bass).

He had a tenor range which was customary at that time, a nasal voice deeply rooted in tango, and an evident vibrato, possibly because he had no vocal training. How many boys with a certain acclaim and even successful, in some cases, never had a singing teacher!

As all the recordings made by Juan Guido were re-mastered and released as compact discs, today we can appraise the performances of the singer.
