This piece is based on the sounds of doors opening and closing. The intention is that real-time doors will start opening and closing in the laneway and mix into the piece. I heard this happen a number of times, but unfortunately did not manage to record an example. Pitch-shifting provides a variation to the typical sounds of closing doors. This also affected air-conditioning sounds in the recording, producing a moaning sound. Note the sound of a trolley being dragged on the ground at 50s; its timbre is similar to that of the installation sounds.
