Brussels was built on a swamp, and today there is only a small part of Brussels that is still officially a swamp. Although continually threatened by development, the area has remained largely untouched due to the fact that it is sandwiched between two railway tracks. Just before first light, filmmaker Jan Locus and sound artist Stijn Demeulenaere recorded the dawn chorus. The drone of the city permeates the sound of the swamp, and a strange mix involves the sound of an awakened nature and the presence of humans.
The urban drone and the birdsong merge into an unfamiliar murmur.
