Recordist's notes
River Alzette flows in a tube under most parts ot town, since the 1910s. At this point it comes to view, in a concrete canal. Water flow is mostly inaudible, but an immense drone streams out of that canal, maybe traffic and industrial noise from the other side of the city. (Sony PCM D50, Primo EM272)
