For three months, I dedicated considerable time to visiting the crane nearly every day, occasionally remaining atop it for hours, both day and night. Integral to the overall acoustic environment is the continuous and dramatic fluctuation of surrounding noises within a 24-hour cycle. Consequently, every audible element, along with the space-sound composition that is divided into four parts, undergoes constant rearrangement. Illuminating the crane at night and the gradual fading of ambient noises, the installation's location shifts: it becomes akin to a small stage without an audience. As night falls, the sounds take on a new interpretation. In this desolate and solitary place, the soundscape adopts its own language, reflecting on the cosmopolitan visions of steel and glass prevalent in "New Cologne." Like a resident from another era returning home, with memories fading, the old watchman stands at the new gates of his city.
