I made this the day before I left Frankfurt. I was alone in an empty flat and it was 4 in the morning. There was a Radisson Blue hotel sign by my window shining through some pretty strong fog making my room quite a weird colour. I sent it over to Fred who was in Tokyo and he listened to it for a minute and then called me and asked if he could play piano over it. He did and then sent it back and that is what this is.
