Fascinated by the interplay of echoes from one past to another, Vincent Dumestre and Stéphanie d’Oustrac found an affinity in the project Mon Amant de Saint-Jean , their very first collaboration, and aimed to make it a unique musical adventure: a recital in which the atmosphere of the chansons of the Années Folles infuses early music with its sweet madness. In 1904, the great cabaret singer Yvette Guilbert was invited to the home of the Casadesus family, the founders of the Société des Instruments Anciens (Early instrument society): the Baroque fraternised with the café-concert.

In 1643 in Venice, Cavalli’s new opera caused a sensation among the audience of the Teatro San Cassiano. L’Egisto takes its name from the piece’s main character, an Arcadian shepherd who is misled by an ambiguous inscription into believing his love is lost. A succession of misunderstandings ensues, along with spectacular pieces of music, a scene of madness and a descent into the Underworld for this would-be Orpheus searching for his Eurydice. The sumptuousness of the music, which masterfully illustrates the emotions involved in a love quadrangle, offers Vincent Dumestre and his cast the opportunity to paint with dazzling colours and virtuoso strokes for this first great labyrinth of Baroque sentiment.

In the seventeenth century, the Ospedale della Pietà in Venice took in young orphan girls who received advanced musical instruction. The concerts given there attracted visitors from all over the world, curious to hear these divine voices which remained invisible, since the girls performed hidden behind the grilles of the chapel gallery. Vivaldi became Maestro de’ Concerti of the Pietà in 1714, and it was his pupils who performed his famous Nisi Dominus.

Boesset, nourished by the 'air de cour' tradition of his predecessors such as Pierre Guédron, took this genre to new heights, creating a truly Baroque aesthetic.
