Mark Bain and Arno Brandhluber – BUG (2009)

The new building at Brunnenstraße 9 in Berlin’s Mitte district was recently hailed by Artforum Magazine as “a retroactive manifesto of ’90s-era hypercontextualism” and, more simply, “gorgeous”. What their praise didn’t recognize, however, is that this mixed-use space is not just something to look at but a building to listen to; passers-by can plug their headphones into the inconspicuous silver jack embedded in the building’s concrete and literally hear the otherworldly orchestrations of the structure itself.
