Brussels was built on a swamp, today there is only one tiny part of Brussels that is still officially a swamp. Although continually threatened by development the area stayed intact largely due to being ensnared between two railroad tracks. Murmur is a collaboration between filmmaker Jan Locus and sound artist Stijn Demeulenaere. Just before first light, they recorded the dawn chorus. The city drone permeates the sound of the swamp, and a strange mix enfolds between the sound of an awakening nature and a human presence.
