An ambitious fresco, this version of “Lorenzaccio” is a hybrid work of remarkable originality. The choreographers have succeeded in creating symbiosis between dance and theatre, giving an intemporal performance sketching a portrait of mankind which has lost its bearings, on a desperate quest, gracefully interpreted by La Pietragalla. January 20th. Palais des Festivas et des Congrès, 1 boulevard de la Croisette, Cannes (04 92 98 62 77).
