Swedish sound artist Ola Sandberg uses the acoustics of Brønshøj Vandtårn, a listed water tower and a pioneering piece of Danish functionalist architecture, as an instrument. Over three days he explores the building's resonance with electronic instruments and improvisation, working on where the speakers sit, the frequencies used and how sound moves through the space.
The project is part of Invisible Room, his artistic research into the relationship between sound, music and architecture. Before Brønshøj he has explored Södervärn's water tower in Malmö and Koncertkirken in Copenhagen. On the third day the doors open to a public listening session, which is not a traditional concert: the building itself becomes the tool for listening, while slowly shifting, simple sound sculptures make the architecture audible.
