Carlos’ life took an unexpected turn when, at the age of 23, he was invited to join the newly formed Les Luthiers ensemble. At the time, he was completing his studies for a degree in Orchestral Conducting, although he loved conducting choirs. His artistic life was a mix of all these ingredients. He conducted operas, symphonic concerts and choral symphonic concerts. He founded and conducted the Estudio Coral de Buenos Aires chamber choir, long celebrated as the most important cutting-edge choir in Argentina. He co-authored the music and text of more than thirty shows presented by Les Luthiers since the 1970s. For several years he conducted the Argentinian National Polyphonic Choir and was an advisor to the Teatro Colón in Buenos Aires. He received countless awards for his individual work and, with Les Luthiers, the Princess of Asturias Award. He is a full member of the Argentinean National Academy of Fine Arts and currently sits on its board of directors.
