Progressive Rock songs with odd time signatures?

I found an online score of this here: https://opensheets.org/sheet-music/machine-messiah/4723.html

If this score is accurate (I only have rudimentary score reading skills), it's going from 9/8 to 7/8 to 12/8 to 15/8 and then repeating that again. Honestly, it's going too fast for me to count it to confirm it (I have a slow brain today). Maybe someone with better ears can confirm what's going on in that section?

If you're looking for more 5/4 stuff

Dün's sole album was "Eros" (1981). The album was inspired by an idea from the Dune series by Frank Herbert, and it is widely considered a masterpiece of French progressive rock. My favourite song, "Bitonio," begins with an xylophone-accented odd time signature and a build-up before launching into its primary piano riff and continuing to expand from there. The song transitions from the main riff to a brief ambient-like part and back again, with amazing flute and guitar performances by the band members Vandenbulcke and Geeraerts completing the picture.

I can not say that I have ever listened to any music for some music this or that ... these "mechanics" are great for teaching things some, but I think that when it comes to handling and trying to tell someone it is this or that, I think it is a problem. 

Having been around many writers, and musicians, a lot of them talk about what, and how, they see the inside, and some were even good enough to kinda describe it as if it were some kind of a movie ... and then one day Daevid said ... let them find the time signatures in the wind! 

In the end, I find that a lot of these details are, often, a matter of comfort and simply trying to do something or other, or in some cases a "mistake" ... but if you are a theatrical type of person and have enough experience with things, "mistakes" are never mistakes ... they usually are a doorway to something else, perhaps new parts for something else.

I tend to turn off material that comes off like ... showing off the signature changes ... as if it were some kind of outstanding musical ability ... which I'm not sure is the case, and it could have happened because someone accidentally dropped a note here or there, and the engineer said ... actually it sounds better than way!

I trust the instinctive design of things, but the mechanical style of a lot of things mentioned here is something that I can not seem to enjoy a whole lot. A good example, is Frank Zappa ... I never really thought about a time signature ... it's just great music, regardless.
