i just grabbed an incomplete mp3 of d-sho qub off soulseek and i bet my ass it's legit...
[spoilers ahead]
in terms of production it's indeed quite close to certain aspects of quaristice: very "spacey" and wide (lots of warm, reverby pads)... BASS! starts off with some ambient chords and bubbly sounds in the bg (metroid-tourian), soon awkward, skeletal BEAT sets in (snares like shots in the dark lol) with more and more percussive effects joining in building an actual groove... bassline sounding very organic, almost like "real" double bass. "qubby" vibe yeah. then an ambient middle section (vangelis/paralel suns style) until beat comes back in a more reduced form and unfortunately soon after that the mp breaks off... all in all it ate my soul. totally awesome! really tempted to look for the rest now although i kinda wanted to wait for the whole experience this time :/ argh... the complete time would be 4:24. i know if this'll turn out to be fake this post will make me look like an ass but like i said i'm very confident, it has autechre written all over it in terms of mood, production etc and it really fits in with everything one has heard about the album so far...
