Video installation created by a trio: photographer Taisuke Koyama × creative collective PARTY × musician Shohei Amimori “GINZA GROUND GAP” is an installation that brings subtle changes to the rooftop garden space through a chain of three media—video, photography, and sound—recorded, shot, and captured in the streets of Ginza. In this work, the scenery at ground level and the view from the rooftop gradually blend together, giving the streets of Ginza and the people passing through them a faint sense of unease and uplift. The video is created from the movement of people striding through Ginza; the photographs from objects on the street surface and those that create boundaries; and the sound from people’s footsteps and the vibrations of the air.
