There's so much going on in this record. The tracks are varied in style and instruments, and there's a lot of intriguing details hiding in the background. I loved the crunchiness of part 9, and the harmonies on part 13 in particular.
The first few tracks conjure up a subtle, shifting atmosphere that reminded me of Tarkovsky's Stalker. Then this track kicks in with a shift in tone to something darker and deeper, which was an interesting change of timbre and texture.
