Swiss composer Oscar Bianchi was the Selected composer at the International Rostrum of Composers in 2016. Partendo (2015) for countertenor and ensemble was selected by the delegates as most outstanding. The work was presented by Swiss Radio (RTS).

As part of his prize, the International Music Council has co-commissioned with Radio France and other partners a work which was premiered on Saturday 7 February 2020 at the festival Présences at the Radio France House in Paris.

The piece was performed by the Quatuor Diotima, one of the most in-demand chamber ensembles in the world today. The Quatuor Diotima has worked in close collaboration with several of the greatest composers of the late twentieth century, notably Pierre Boulez (who revised his Livre pour Quatuor for them) and Helmut Lachenmann. The quartet regularly commissions new works from the most brilliant composers of our time, including Toshio Hosokawa, Miroslav Srnka, Alberto Posadas, Mauro Lanza, Gérard Pesson, Rebecca Saunders and Tristan Murail.
