hen he was a kid he began to study violin with a printed method in his hometown, Grütley Norte (province of Santa Fe). His father was an intuitive musician. He played tango pieces and music of other genres of popular music on his bandoneon. Miguel Ángel wanted to learn to play accordion —an instrument that for them was impossible to buy—, because of that his father bought a violin so that he would get in touch with music.

In order to improve his command on the instrument he began to take classes with maestro Juan Benesovski in the nearby city of Esperanza. Soon he started to join orchestras of amateur musicians that played at the balls held in the area. He began his career by joining tango orchestras in 1957.

Some years later he moved to the city of Santa Fe to further his studies on the instrument and, in 1966, he joined the Orquesta Sinfónica de Santa Fe. In 1969 he joined the Symphony Orchestra of the province of Entre Ríos.

After overcoming certain technical and personal difficulties—thanks to the guiding hand of maestro Salas—, he again joined the Orquesta Sinfónica de Santa Fe and, some years later (in 1976), the orchestra of the Teatro Colón and as from 1977, the Orquesta Sinfónica Nacional (National Symphony Orchestra).

At the same time he had a career in classical music he belonged to the world of tango. He recorded with maestros Osvaldo Berlingieri, Néstor Marconi, José Colángelo, Leopoldo Federico, Horacio Salgán, Mariano Mores, Atilio Stampone, Carlos García, Osvaldo Requena, Julián Plaza, Lisandro Adrover, Víctor Lavallén, the vocalists Roberto Goyeneche, Alberto Podestá, Susana Rinaldi, among others.

In 1994 he was summoned, as lead violin, for the Forever Tango show when it was premiered in Beverly Hills. For four years he joined the Tango Argentino company.

In 1998 he appeared as soloist with the prestigious Boston Pops Orchestra at the Symphony Hall of Boston.

He has carried out a busy schedule as session player alongside figures like the prestigious violinist Fernando Suárez Paz, member of the Astor Piazzolla Quintet, with whom he recorded Cuerdas para Piazzolla and Concierto de Nácar with the Orquesta Sinfónica de Buenos Aires.

He cut three CDs with Forever Tango, besides appearing in recordings with Osvaldo Requena, Lisandro Adrover and Fernando Marzán, among others.

On the disc Coincidencias he shared the responsibility as soloist with the bandoneonist Leopoldo Federico: “Bendita Buenos Aires”. Furthermore, he recorded his own projects along with the pianista Elisa Muñoz: Cristal de Tango and A call from excellence.

He has played solos in the movies The Impostors directed by Stanley Tucci; in the documentary by Steven Spielberg Survivors of the Shoah: Visual History Foundation; in Convivencia and La fuga, as well as in other important Argentine productions.

He appeared as soloist at the musical Tanguera with the quintet led by Lisandro Adrover and made important appearances in Argentina and Europe.

Furthermore, since the time of its inception he has been joining the Selección Nacional de Tango and was requested to appear —along with the greatest tango figures— in the Orquesta Café de los Maestros.

At the Festival de Tango de la Ciudad de Buenos Aires in 2011 he appeared for the first time with his tango orchestra which was lined up as follows: Carlos Sanguino, Fabián Bertero, Gustavo Mulé, Gustavo Bertero, Pablo Borzani, María Laura Bertero and Sergio Polizzi on violins; Claudio Melone on viola; Diego Sánchez and Patricio Villarejo on cellos; Horacio Cabarcos on double bass; Ramiro Boero on bandoneon and Elisa Muñoz Bertero on piano.

On that occasion the disc A mi querida Buenos Aires was introduced. It is a heartfelt homage by Miguel Ángel Bertero to the city whose neighborhoods and streets he imagined in his hometown when he was a kid and heard the tangos that name it when he was with his father that used to play them on bandoneon.

The disc was recorded in ION studios, was published by Sony Music and had Leopoldo Federico and Lisandro Adrover as special guest artists.

Maestro Leopoldo Federico said the following about Bertero: «We met at a recording studio several years ago and since then I was caught by his sound and his quality as interpreter. Lately he played as soloist in the disc we recorded with my dear Osvaldo Requena in a production with numbers by Osvaldo and mine and I was amazed by the solos he played... Among the group of violinists that lived and live and are the greats in the history of tango, Miguel occupies, undoubtedly, a well-deserved place and is recognized by his peers. I’m very happy and proud of having collaborated in his latest CD and of being his friend».
