Huge sediments of vinyl, CDs and paper buried this release for many months, so that some words about that are maybe too late, even if it should be available yet as a digital on the label/artist's Bandcamp... and if you missed like I did, I recommend to grab a copy. The use of the word 'sediments' and its connection to geology is not casual of course. I heard the sound by Fabrizio Matrone in the guise of Matter on the occasion of the release of "Biorhexistasy" on Kvitnu, whose title was a reference to the theory by Henri Erhart, a pedologist who proposed a general theory about the relation between climate changes and soil transformation on the basis of the alternation of biostasy and rhexistasy, a set of climatic conditions causing soil formation and soil erosion. The coexistence of the tangibility of stones, rocks, mud and weather events as well as their seemingly chaotic interaction in the seemingly ordered box of an abstract theory mirrors the feature of the sounds explored by Fabrizio on "Margins" as Heidseck, as well. The seven tracks are mainly based on glacial drones, that could vaguely resemble those field recordings that some adventurous forgers of the genre grabbed in extremely cold regions, whose gradual but continuous progressions over a gravel bed of muffled thundering of very low frequencies and white noise. These streams of abstract sounds sometimes extinguish like a candle in a room without oxygen (on tracks like "Medial" or "Blockfield"), sometimes evolve into something else like dim brighter whispers ("Lateral") or crumbling implosions ("End"), but any transformation keeps on rendering an idea of a subtly deceptive impermanence under an obscure mantle which doesn't succeed in covering the jagged edges of Heidseck's sound.
