Can’t say much about that Shostakovich reference. But damn dose it just ooze ambiance.
Somehow this could be straight out of an atmospheric game like Journey. Maybe Journey in the nordic mythology of the Edda. Stumbling thru the icy wastelands of the ice giants.
It really sounds solid. The instruments sparkle with presence while the reverb swallows it all and leads us into the atmosphere at hand. The to different tone colours of your Kantale and Lyre balance very nicely and get complimented well with your choice of strings. Your experiment with two reverb buses worked yout very well and I'm quite hopefull on hearing more of that.
Very well done!
