Italy's Cristiano Deison is a musician active since the mid 90's in the noise / experimental / ambient realms. Many of his releases are collaborative works among them quite known names like John Duncan, K.K. Null or Maurizio Bianchi.
This EP is part 28 of the ongoing Substantia Innominata series by Drone Records.

Substrata features three new atmospheric compositions based on prepared tapes, metals, strings, wires and electronics recorded on different locations assembled and processed afterwards.
"Terra Firma (Pt. 1 & 2)" is a 16 Minute exploration of organic development, split in two parts. A soft, soothing ambience develops slowly until clear, crystalline sounds evolve and together with calm pulsating deeper sounds which shape together the picture of an acoustic stalagmite cave.
With "Prima Materia" he tries to describe "the primitive formless base of all matter similar to chaos, the quintessence or aether." A bold aspiration which leads to an more diverse soundscape but bearing the same smooth tranquillity. Starting with the same crystalline sounds embedded in a mysterious distant rhythm it shifts into soft ambient paired with distorted everyday noises. A collage which equally occupies the senses as "Terra Firma" and passes faster than the track length suggests.
Side B closes with an short afterthought, "In Vacuo Momentum", which plays with channels and sounds leaving the impressions of passing whales deep down in the Ocean.

Deison's compositions have an very organic feel to it, illustrated on the cover with what could be a spiderweb on a rusty fence hit by raindrops. The green, transparent Vinyl of this edition of 300 supports the artistic vision appropriately.
