Concrete lovers should get over to Brunnenstrasse 9 to introduce an aural aspect to their material fascination. Via a headphone jack in the wall, passers by can plug in to hear ambient rumbles from deep growls to high pitched chirps and gentle murmurs, coming from the bowels of the building.
Generated in real time by seismic vibration sensors, the sounds are the concrete's experience at that time, its physical movements as you're standing next to it listening to its inner life, stimulated by passing underground trains and more subtle atmospheric traffic like lifts and aircon, converted from feedback vibes into noises.
Whilst tweaking the gallery space on the ground floor, the architect Arno Brandlhuber, whose offices are now in the building, told me that he got the idea at an architecture festival and subsequently invited the artist Mark Bain to come up with a permanent sound installation - which he did, and called it Bug.
