The first chapter of this series is "Zastrugi" - the first techno glacial album by Netherworld. It's a wind-eroded, hard-packed snow surface with irregular grooves and sharp ridges that is mostly found in the earth’s polar regions as well as on high mountains subject to high winds. The ridges, often appearing like frozen waves, form parallel to the prevailing winds and are usually found on windward slopes. The windward surface is usually rough and has a sand-blasted appearance. The snowy surface is very hard and is difficult to cross by foot or on skis. Netherworld aka Alessandro Tedeschi is also the creator and owner of Glacial Movements Records in Rome, Italy. He published several works on various labels such as Fario, Angle Rec, Umbra, and Taalem, The Wire Tapper Series and Glacial Movements with releases like "Morketid" (2007), "Over the Summit" (2011) and "Alchemy of Ice "(2013) .These were critically acclaimed gems of ambient music.
