The audience is led into an unusual, intimate, green space, where the atmosphere is timeless and silent ... for a moment. This show is a fusion between the power of the sound wave and the lightness of the Alchemist's manipulations. Using their unlikely instruments, the actors of the Cie du Petit Grimoire take their audience on a brief journey through time, through the twists and turns of their imaginations. Will they succeed in transforming ordinary metal into gold? The story begins... Master Albertius, the Purveyor of Secrets, and Phylarcius, the Maker of Sounds, meet again. The setting has been frozen for over 500 years, as if by magic. The Petit Grimoire opens, formulas fly out, spirits gather and the elements are unleashed... . With Stéphane Borel and Manuel Gleyre
