I stand still listening to wavy chants performed by a muezzin in a little town of Bil'in in Palestine. Reinforced by a low quality amplifier his voice slides over the concrete plainness of the walls somewhat ignoring their impassioned will to divide. His voice soon finds an alliance with a breeze, similarly reluctant to the material constraints. Its vitality becomes evident once it encounters a flock of dry leaves, yet another family of increasingly deterritorialized, organic entities. Here, more then anywhere else, the aural seems capable of withstanding physical limitations, breaking through the barriers and evading any attempt aimed at its rigid delineation.
