This video has been realized by Alessandro Quaranta in the summer of 2011, in a mountain area in France, near the Italian border.
He appointed several young people to watch down the valley, from various locations corresponding to surveillance spots as fortresses and army bunkers, that were active during the 2nd World War. Each one of them was given a different device, such as binoculars, video and photo cameras. Alessandro just told them, rather vaguely, about 'something' that would happen somewhere in the valley, asking them to pay the greater attention, in order to catch that untold but important event.
Some time before the day determined for the action, Alessandro assigned a 'sonic anthropologist' to instruct the youths about how to listen to the various sounds and noises coming from the landscape, in order to learn how to keep watching during the action.
That day the action took place in 3 hours, around noon, and all the gestures of the young people watching around them, with or without their watching devices, had been shot by four professional video operators, who also took care of recording the surroundings sounds, as well as the voices of the youths.
For "The Changing of the Guard" version presented, for the first time ever, in the context of Frownland (see http://www.estatic.it/en/content/frownland-ii-events-dense-fog-craddock-niblock-pugno-quaranta), Alessandro did an editing of all the audio and visual material, trying to emphasize the sense of suspense pervading the whole situation which occurred that day.
