It is sixty years since Pierre Schaeffer started “musique concrète” in Paris. But what is concrete music today? Who are the composers who perform it? A reply to these two questions comes from this musical encounter of Tempo Reale, headed by Daniel Teruggi, composer and Director of Research, INA/GRM, the institution founded by Schaeffer himself. He led the listeners in a journey through the present day and the history of a musical genre which has had no mean influence on contemporary languages.
