The spectral features of the seven bells at the Basilica of the Holy Apostles in Cologne, which were transformed and spatialized through an algorithmic process, were a starting point for this work specifically conceptualized for the Minoritenkirche Krems. “Glockenbuch II“ forms an imagined sound bridge between the two cities Cologne and Krems, since church bells always serve as a kind of acoustic landscape that enables orientation within a city.
