The Libretto Festival was inspired by the theme of the Arteplage Murten-Morat, Moment and Eternity, and invited visitors to take a surprising journey into the world of classical music during the day and in the evening. The concerts and performances took place on the lakeshore, on the Arteplage, in the Tente Centenaire, on a mobile stage and at various locations in Murten-Morat (streets, squares, churches, town hall, etc.) and were organised like an itinerary.

The music of 676 Nuevo Tango moves towards the exciting frontiers of tango and jazz, thanks to pieces by Astor Piazzolla and the group's own compositions. Each of these five highly acclaimed musicians brings his or her own musical background to their music, creating something new and unique.
