His international career began in 1946, where he debuted in the city of London, and reached later more international stages such as in the USA, in Canada and in Latin America. He also created the Arezzo and Bolzano masterclasses, joined by young performers from all over the world. In 1955 he was invited to be part of the jury of the prestigious Piano Competition “F. Chopin” in Warsaw.
Towards the end of the ‘60s, due to financial problems, Michelangeli left Italy and moved to Switzerland, where he continued to practice his art and started a long collaboration with the record company Deutsche Grammophon, which created amazing recordings.
In June 1980 he came back to Italy after his exile, on occasion of the concert in the Teatro Grande of Brescia, in memory of the Pope Paolo VI; this would be his last concert in Italy.
