Amour, the messenger of the gods, tells Orpheus that he may descend to the underworld and return with Eurydice. His singing has the power to appease the Furies and animate the blessed Shadows. Yet, his voice cannot reassure Eurydice who despairs of the feigned indifference of Orpheus, put to the test by Jupiter. Raphaël Pichon conducts the opera of operas and Aurélien Bory displays the giddiness of the mental and supernatural spaces traveled by Orpheus and beyond. Marianne Crebassa plays a new breeches role with Hélène Guilmette (Hélène in Le Timbre d’argent) and Lea Desandre (the title role in Alcione).
