Review: "Polar Sequences" has always been one of Biosphere's most icy and evocative albums. It first appeared in stores in 1996, though its roots lie in a collaborative performance that took place atop a mountaintop in Tromso - Biosphere's home city - a year earlier. Alongside Bobby Bird of British ambient techno outfit Higher Intelligence Agency, the Norwegian crafted a unique live show that blended chilly, windswept ambient textures and gently unfurling electronic melodies with re-processed field recordings of Tromso and its surroundings. As an album, "Polar Sequences" subtly refined and reworked this performance with breathtaking and spellbinding results. This reissue contains all six tracks from the original release, as well as a worthy bonus: the original 14-minute field recording that provided the basis for the original live show.
