I never realised how much a train sounded like a plane. Or why travel makes us feel stress. Us all too busy. The train slowing down is like a plane taking off. Why is the station so quiet? Where are the people?

There are sounds that are not native. What would happen if they played birdsong on the underground? Is that why people like to hear buskers? – a small reminder of humanity?

I can smell the stale air. I can feel the dirt on my (illegible). Noise is pollution…keep moving – keep moving. Keep moving.

Now it sounds like a beating heart. Boom swish boom swish. Alive they living underneath us. Now the music. I’ve been waiting for the music. Simon & Garfunkel. Mrs Robinson.
