Biosphere's Dropsonde was part of his catalogue of deep ambience. Though beloved of listeners of aquatic, immersive techno, Biosphere also found his music regularly heard in TV adverts and idents. Nothing that should put you off delving into this re-issue which adds seven previously unreleased recordings to the package. Otherworldly bliss throughout.  Widely regarded as one of Norwegian electronic music's most important artists, Biosphere's [Geir Jenssen] career spans nearly two decades, several albums, lots of remixes, various sound installations, commissions, soundtracks and even the odd Himalayan summit. 

You may recognise his work without knowing it, so frequently does it crop up on TV trailers and idents. In the early 1990s he was a pioneer of so-called 'Ambient Techno', but since then, he has refined his sound into something more magnetic and enduring. The spatial aspects some have dubbed "Arctic sound" but it summons strong feelings, or as Exclaim from Canada put it, "in order to climb higher, you must first go deeper". Jon Savage adds: "As with all of the Biosphere albums, the music draws you in and makes you want to listen and feel. Jenssen's work acts on a very emotional level, one that encourages you to drift away into a haze of images and scenes brought to you by the music, where spectacular beauty hides unseen danger. Intense and moving, but comforting and soothing at the same time."
