River waves and a folk musician

On the river path one walks though short tunnels under bridges, beside river beaches, more tunnels and open spaces in very quick succession. All have a different soundscapes and an acoustic character that constantly change according to weather tides, time of day, season and people's activities. Here the waves slosh on a beach fast disappearing under the rising tide as a folk musician plays in the tunnel under the road. He taps the beat with his foot. There's a certain rhythmic similarity with the waves.
