The majority of the streets in the centre of Ponta Delgada old town are made from cobbles of volcanic rock. The narrow streets with tight corners frequently result in the sounds of squeaking rubber.
It was relatively quiet in Ponta Delgada as I was there outside of peak tourist season. The second recording, made early one evening in a quiet side street, features rustling leaves, occasional pedestrians and the music from a nearby bar.
In order to try and avoid traffic sounds, I made some early morning recordings at the marina in Ponta Delgada. It was quite windy and in the third recording you can hear the boat rigging clanking as it is blown in the wind.
