Biosphere is the main recording name of Geir Jenssen (born 1962), a Norwegian musician who has released a notable catalogue of ambient electronic music. He is well known for his "ambient techno" and "arctic ambient" styles, his use of music loops, and peculiar samples from sci-fi sources. His 1997 album Substrata is generally seen as one of the all time classic ambient albums.
The project is named after the Biosphere 2 Research Project, which was meant to test the possibilities of building self-sufficient space colonies, and hosted entire families living in a completely detached environment for years.
Geir Jenssen's Biosphere has likewise been steadily creating a self-contained aural universe. Once inside, we will experience the outside world through the spherical window. As if watching a movie where, despite the monumental scale, we still manage to feel we belong in the script.
