Apr. 1995, at street of AOYAMA in Tokyo

I installed this work in public space at several street trees put up sign boards. This work is a small unit for minimal sounding system consists of a small loudspeaker for headphone, a small dry battery and thin wires. I connected the wires with the clasp of the sign board in order to make up electrical contact points. At the points, the unit caught up the various physical vibration from window, traffic and so on as an aspect of street factors. The sound is generated by the contact electricity intermittently occurs at the points.
