The album was not really meant to be about anything in particular since there are no lyrics or overt themes, but if I had to choose a subtext for it, it's an album that celebrates the future, particularly science and technology.
If you buy this album, thank you so much. You don't have to pay for it, but if you think it's worth something than I'm grateful that you think so. However, I don't mind if you download it for free, since it means at least you enjoy it enough to give a small portion of your hard drive space to it. If you enjoy it, please spread the word. If you don't, hopefully next time around I can make something that you're more into.
