Funnily, Koyaanisqatsi ranks on the lower end for me for Glass works (no pun intended). I’m a huge Glass fan(atic perhaps), and much prefer stuff like Truman Sleeps, Mishima, Jane soundtrack, Glassworks, Symphony #4 Heroes (Glass/Bowie/Eno), Mad Rush, etc etc. His music composed specifically for the piano is gorgeous.

Amy Dickson’s saxophone interpretations of his violin concertos are absolutely riveting, example: https://youtu.be/ZdUWPA_AX6o

It's interesting that there are two fan groups of Glass' music with almost no overlap. Qatsi trilogy is also on the lower end for me, but my favorite pieces are his more experimental works like Einstein on the Beach. Most of his Hollywood soundtracks are way more conventional.

The soundtrack from Mishima: A Life in Four Chapters is absolutely incredible, just like the movie as a whole. I've been looking for a way to get prints of some parts of the movie, the last blu ray from Criterion has a small booklet with a few pictures from the sets, but they're very small.

AI upscaling works incredibly well in my experience.

Is there any in particular that you would recommend? I'll admit that I have a negative prior for AI upscaling, as I've seen a few cases in I think iPhone pictures where the AI added things that weren't there. Ideally I'd like to find the original pictures of the sets, as either they will be digital, or can be digitized without losing anything, but it looks like it would require a trip to the USA at the E. Young Research Library, and I'm not even sure I would be allowed to take copies.
