Octavio studied classical piano at the National School of Music in his home town Rosario, Argentina. Before graduated, he was already performing a variety of music styles. But his love for the tango prevailed and soon he was playing with many of Argentina’s most important tango musicians and singers, such as Alberto Castillo, Eladia Blazquez, Ruben Juarez, Domingo Federico, Rodolfo Mederos, Osvaldo Piro, and shared the stage with Horacio Salgan-De Lio, and Atilio Stampone. He co-arranged for the piece “LEVANTE” by the famous Argentine composer Osvaldo Golijov and while still quite young, he performed at the world-famous Teatro Colon and the Teatro San Martin in Buenos Aires, in addition to performances at Teatro San Martin in Cordoba, Argentina. In 2002 he was named conductor of the Provincial Orchestra of Popular Music in Cordoba, Argentina.
 After an extensive European Tour he decided to come to the United States where his participation in New York’s International Tango Competition won him two first prizes: Best Solo Pianist and Best Duo.
He now successfully tours with his own band, the Octavio Brunetti Quintet, and is one of the most sought after tango pianists of our times.
His recordings include “Saludos” with Domingo Federico; “Tierra y Asfalto” by Brunetti-Carballo; “Inquietudes”; with the Omar Torres Quintet; Soledad by Astor Piazzolla with world-renowned cellist Yo-Yo Ma (“Appassionato” by Sony BMG-Classical), and  Grammy Award Winning CD “Te amo Tango” with Raul Jaurena. Most recently he has performed with Yo-Yo Ma at the international Tango Conference at Harvard, Cambridge.
