A short synthetic excursion to the most likely place in our solar system to have life (besides Earth): Europa. Jupiter’s moon (one of many) is slightly smaller than our
moon, and is made of silica and water ice. It’s also believed that the atmosphere consists primarily of good old oxygen. Not a lot of it, because it’s too small to have much gravity, but oxygen and water seem to serve the needs of life on Earth pretty well…

Very bassy, spacy, and arpeggiated. Enjoy.
