A hundred kilometers from Moscow, in the middle of the forest, there was a giant strange spherical chamber with a diameter of 20 meters. Nobody knows exactly where it came from and why. It is a soviet artifact from the cold war age. The sound waves run and interfere in an unpredictable way inside the sphere. Any sound is repeated many times, amplified and lasts unnaturally long. The chamber is unique echo, delay and compression acoustic effects with non-linear subtle parameters. There we found and recorded an interstellar space between the trees. In the winter of 2021 the globe collapsed. This record is a sound memorial of that mystery place.
