I spent many hours on this track over the course of 2.5 years. It's made up of oscillating synth lines, spread over the course of 10 mins. This version is slightly truncated to fit with a video i shot on my phone during the 2020 pandemic, stuck at home in south London and looking north across a storm-struck city. The full-length version can be found at the link below.
It lived with different versions of the track for a long time, walking around my local park with it in my headphones, trying to get my head around the mix and structure. After much deliberation and messing around, I decided on the version you hear.
