ince early age he evidenced his inclination for singing. He studied with maestro Bonessi and he frequently performed at clubs in his hometown: Chacabuco, province of Buenos Aires.

Between 1952 and 1957 he joined several local groups, the first was the one led by the violinist Roberto Betular, later came the Orquesta Splendid led by the pianist Ismael Etcheverry and finally, a line-up led by another pianist: Héctor Marssiletti.

Because he applied for a contest for new singers organized by Radio Belgrano, the members of the board of the radio station, after hearing him, hired him for the staff orchestra that was conducted by maestro Leopoldo Federico.

In 1965, he performed with the accompaniment of a guitar group led by José Canet at Patio de Tango, previously La Armonía tea room, on Corrientes Avenue. At the same local the Osvaldo Piro Orchestra was playing and, coincidentally, was looking for a vocalist to substitute for Carlos Nogués who had switched to the Héctor Varela's orchestra.

The following year they appeared at the Festival de Tango de La Falda to great acclaim. With Piro he made his debut on record with four numbers for the Alanicky label in 1965: "Dice una guitarra”, “Enamorado estoy”, “Mimí Pinsón”, and “Por unos ojos negros”.

They played on television on Channel 13 at the famous program emceed by Nicolás Mancera, Sábados Circulares, and in 1968 Osvaldo Piro was awarded the Martín Fierro prize as the “Musical Revelation of the Year in the Argentine Television”.

That same year they cut four recordings, this time for Philips: "El puente”, “Duerme mi amor”, “Milonga triste” and “Un regalo de reyes". The long-playing record also included other instrumental hits by the Piro’s orchestra.

In 1969, the vocalist Alberto Hidalgo joined the orchestra. With him they opened the night venue Michelangelo in the neighborhood of San Telmo. They toured Brazil and Uruguay alongside other great stars like Roberto Goyeneche and Horacio Deval.

Now as soloist he appeared at Grandes Valores del Tango, an important TV show conducted by the "chansonnier" and actor Juan Carlos Thorry. Because of that he was awarded “El trébol de oro” by the sponsors of the program.

He made tours throughout the country and he continued appearing on television and at different venues in Buenos Aires.

1975 was a very important year for his career. The singer Oscar Ferrari split with maestro Armando Pontier and after Alberto Podestá’s suggestion he was requested to replace the former. The debut was at the mythical Cabaret Marabú. They later traveled to Chile on a tour that lasted 35 days.

With Pontier he appeared on television and on Radio El Mundo, at dancings of important clubs and cut six numbers for a record: "Buenos Aires", "El hombre que fue ciudad", "Clavel del aire", “Selección de tangos de Gardel y Le Pera”, "Anoche” and “Cuando tallan los recuerdos".

In 1979, he made a four-month tour of Brazil. María Graña and Enrique Dumas were also members of that artistic embassy.

In December 1983, the tragic death of maestro Pontier took place so Carlos Casado came back to work full time as soloist. Some time before that he had opened a night local, Bien Porteño, where he sang accompanied by a group led by Orlando Trípodi. Some of the artists that appeared at that venue were: Armando Pontier, Roberto Goyeneche, María Graña, the guitarist Bartolomé Palermo with his outfit and many more.
