I have spent longer periods of time getting from point A to point B but the longest single flight was a trip from Newark to Tokyo. I was sure, given the duration, that I would be able to grab a little shut eye if not from fatigue at least pure boredom but I was awake the entire passage.
I studied my conversational Japanese and wrote this song. Rather than using my typical means of production, I arranged and recorded it with a free version of Ableton Lite software. It was a challenge to fit everything into the limit of 8-tracks and, frankly, learning Japanese was more intuitive but the software helped me achieve an ethereal sound that works for the theme of the tune.
