Substrata 2, also written as Substrata², is a double album by ambient musician Biosphere which was released on 6 June 2001.
The first disc is a remastered version of Substrata, and the second disc is a soundtrack for Dziga Vertov's 1929 film Man with a Movie Camera, commissioned by the Tromsø International Film Festival in 1996, plus two bonus tracks from the Japanese version of Substrata (the last two tracks).

Shenzhou is an album by ambient musician Biosphere released on 3 June 2002. The structure and sound of this album are drastically minimalistic in comparison with Geir Jenssen's previous work, a concept that would be further elaborated upon in the next album. Samples are taken from several of Claude Debussy's orchestral works, particularly La Mer and Rondes de printemps (from Images pour orchestre). The album's name, "Shenzhou", aside from meaning "magical boat" (神舟) and being the name of the Chinese manned-spaceflight vehicles, means magic vessel. However, it could also mean "the world" (神州).
