Daisuke Ishida explores space solely by means of sound. The artist creates and shapes architecture, the forms, boundaries and volumes of which are strictly of an acoustic nature.

An omnidirectional loudspeaker buried beneath the ground of Friedrich-Wilhelm-Platz creates a hemispherical sound space, the size and tension of which is defined by the loudness and sound patterns emitted. Set within a busy public space with heavy traffic, the artist prompts active listening in the passer-by by introducing synthetic sounds with no evident source, that stand out against the urban acoustic signature. Through this accentuation the listener is made aware again of the daily urban soundscape.
