This is Villa-Lobos-ian Brazilian Impressionist tone painting of the highest order, extraordinarily well orchestrated. and evocative of the lushly exotic Amazonian canopy as only perhaps Villa-Lobos understood it. I still think the old United Artist LP of the complete soundtrack is a killer but this version of the suite is quite nice and representative.
And then you get to hear the related Glass work, some ten minutes of Minimalist slanted Amazonian expression, so that is a definite plus.
Take a look at a brief video for a taste of the music https://www.youtube.com/watch?v=smjXGM3OWKI&t=4s
