This is Fucking incredible. Seriously. This is the kind of shit I spend hours on obscure electronic music sites digging through shit to find. I loved the entire thing, from beginning to end, and I have no criticisms.
However, you said you wanted feedback, so as a fan of this kind of music, I will tell you what stood out most for me:
(~6:47 to ~7:50) — I was already enjoying myself immensely, but I peeked up quite a bit right around here. The vocal sample (if I'm hearing it right?) seemed to add a new dimension to the music.
(~10:26 to ~15:00) — I love this... the hypnotic quality of the kind of chopped up arpeggio is just beautiful. This section really
reminds me of something... some artist or song that I love the shit out of... but it's eluding me right now. Could it be Boards of Canada? I kinda don't think so, and if it is I can't think of the track that this brings to mind. I'm not saying it's derivative — just that the sound (which I can't identify because as much as I love bleeps and bloops I know fuckall about synths and equipment) is familiar. Can you speak at all to your inspiration for this segment of the track?
(~16:35 to ~20:00; 23:00) — Ok, see, I thought the song had peaked. Then this build starts. Your transitions are flawless. I would never have guessed that the piece was going to go in this direction based on the start. Then at ~23:00 it touches on perfection. I'm rubbish at identifying the tones (sorry!) but this is dope as fuck.
(~27:35 to the end) — Heating up like crazy again a little after the 27 minute mark. Then the lower tones that start to blend in at around 31:00, along with the vocal samples, make for a very vivid sound collage indeed.
I don't really know what else to say man. I wish I could give you more constructive feedback, but fucking WELL DONE.
ETA: It reminds me of Tortoise - "Djed."
