The recording is from April 17, 2025. The recording point was chosen under the iron bridge that crosses the Tiber River near the town of Pretola a few kilometers from Perugia in Umbria. Interesting reflections and resonances are created under the bridge. Water is certainly the dominant acoustic element but its veil is constantly torn by a multitude of sounds. 

The bridge, despite being located in a densely populated and busy area, isolates the urban environment creating a capsule of natural sounds.

Recorded by Nicola Fumo Frattegiani.
