Substrata is the third studio album by Norwegian electronic musician Geir Jenssen under the stage name Biosphere, released in 1997 by All Saints Records. It is Biosphere's first truly ambient album, and has a theme of cold, of mountains and glaciers, and of running water. Sounds of howling wind and creaking wood, although infrequently employed, create a chilling soundscape interrupted by sonorous but quietly suspenseful music. In 2001, the album was re-released in a digitally remastered format with a second disc featuring a soundtrack for Dziga Vertov's 1929 film Man with a Movie Camera, as Substrata 2. Reception Substrata is considered to be a classic ambient music album, consistently ranking in the top 5 in surveys on the Hyperreal ambient mailing list. In 2016, Pitchfork ranked it at number 38 on its list of the 50 Best Ambient Albums of All Time. Track listing Samples Track 4: "The Things I Tell You" – speech from Twin Peaks (Season 2, Episode 1) spoken by The Giant on his second visitation to Agent Cooper: Sorry to wake you.

Track 6: "Hyperborea" – speech from Twin Peaks (same episode) from the scene where Major Briggs explains his vision to his son, Bobby: This was a vision, fresh and clear as a mountain stream, the mind revealing itself to itself. In my vision, I was on the veranda of a vast estate, a palazzo of some fantastic proportion. There seemed to emanate from it a light from within, this gleaming, radiant marble. I'd known this place. I had in fact been born and raised there. This was my first return. A reunion with the deepest well-springs of my being. Wandering about, I noticed happily that the house had been immaculately maintained. There'd been added a number of additional rooms, but in a way that blended so seamlessly with the original construction, one would never detect any difference. Returning to the house's grand foyer, there came a knock at the door. My son was standing there. He was happy and carefree, clearly living a life of deep harmony and joy. We embraced, a warm and loving embrace, nothing withheld. We were, in this moment, one. My vision
