As Ray said, “Cosmic utterances in a very spacey/psych setting.”
The audio and the video are sort of other worldly and we could hear this in a sci-fi movie soundtrack.
The juxtaposition of the unsettling feel of the slower tempo sections helped serve the lyric sadness well.
Sounds like a world of vocal processing that is well beyond our comprehension paygrade.

Y’all are on a roll!
