Register des Universums – Organ Sounds from the Universe – Teaser

Our moving journey through the universe illustrates the uniqueness of no less than planet Earth. Infinite expanses, darkness, emptiness. Nothing could be stranger to us humans. We take our visitors on a mighty journey through space and time. Goosebumps are guaranteed. Experience the universe in its artistic splendor and scientific beauty. Feel the power of the organ and the colorful sounds of the extremes. Our destination: Earth, a lonely speck of dust in the light of the sun, a lonely spaceship in the middle of the deep and empty universe. For the universe our Earth is hardly significant, but for us it is everything. It seems the universe has pulled all the stops.
