“Sound-Track: Routed Wheels” is an experience that subverts the conventional perspective on listening through a sound walk. Recording equipment is installed on the omnipresent trolley of Tai Kok Tsui, exciting auditory awareness through the progress of transportation. As the wheels roll, tracing their path, they collect a variety of sounds—from the hustle and bustle of the city to the whispers of the crowd. Participants are invited to become the loadings on the trolley, uncovering the loud and subtle aspects of life beneath the tracks.
