In 2019, São Castro and António M Cabrita are invited by the Théâtre de la Mezzanine (France) to take on the choreographic direction of the opera Orphée et Euridyce, staged by Denis Chabroullet. In this approach, the director takes advantage of the myth of Orpheus, with the tender and sulphurous gaze that characterizes his theatrical universe: exploration of materials, energy of bodies, infernal machines, his tools are sharpened to accompany Orpheus' journey through the underworld.

A theater of music and imagination, with its appearances and disappearances, pulleys and traps, where the confusion of feelings makes us oscillate between the intoxication of a mad love that hesitates to fulfill itself, and the sulphurous power of darkness that infuses itself every day in the interstices of our real world.
