Bataille is a confrontation between two physical actors : on one hand Hassan Razak, specialist of body percussion and on the other hand Pierre Cartonnet, specialist of acrobatics. This confrontation is a complex, paradoxical and ambiguous battle. Is it a realistic dance or a choreographic fight ? Is it a contract accepted by both parts or a unilateral violence ? Is it a fool’s game ? Is the violence undergone or granted ? Masochist or sadist ?
