There are some places in that where it sounds to me like there is someone singing a repeated three syllable word with one syllable on each hit of the 3 notes on the left end of the top row and sung at the tone of that note. Anyone else hearing illusionary singing in there? The place I first got that illusion was around 3:24, and I was listening with my eyes closed which I think might make it more likely to hear issusions.
