Percussive Plane - The photograph is of a large glass wall which I associate with large train stations.A large percussive surface exposed to wind, debris, rain, drizzle, sound waves and in the case of this photograph, man made noises from maintenance crews such a work ropes, glass cleaning tools and impacts. This large glass surface acts like a reflector amplifying the sounds that reach it. Found sounds where used to construct the soundscape.
Photograph by O.W. Chow - Cleaners maintain the transparency of the glass windows, Pudong International Airport.
