The Amarillis Ensemble, recognised as one of the most on-the-pulse baroque music groups on the French scene, is celebrating its twentieth anniversary by creating La Double Coquette as a musical: a story in the Marivaux style, and above all an ambitious creation combining the baroque world of the French composer Antoine Dauvergne (1713-1792) with the music of the great contemporary composer Gérard Pesson and using a libretto by the poet Pierre Alferi.
