Progressive Rock Album List-1975

I love to see these kinds of polls. :)

I saw this right after submitting my 1975 list to AwesomeProg (been working my way down the years) https://awesomeprog.com/release-polls/pa/aoty-1975/users/Logan. It needs more work, but here is my top 20 of 60 from there right now as I see Mikes also shared his. The order is very flexible, will be adjusted more, and generally loosey-goosey.

1. Cortex - Troupean Bleu
2. Hatfield and the North - The Rotters' Club
3. Pink Floyd - Wish You Were Here
4. Tangerine Dream - Ricochet
5. Neu! - NEU! '75
6. Harmonia - Deluxe
7. Van Der Graaf Generator - Godbluff
8. Led Zeppelin - Physical Graffiti
9. Area - Crac!
10. Klaus Schulze - Timewind
11. Hawkwind - Warrior on the Edge of Time
12. Vortex - Vortex
13. Lula Côrtes e Zé Ramalho - Paêbirú [AP Prog]
14. Henry Cow - In Praise Of Learning
15. Richard O'Brien - The Rocky Horror Picture Show [AP Prog-Adj]
16. Egisto Macchi - Contemporanea [AP]
17. Dzyan - Electric Silence
18. Slapp Happy - Desperate Straights (with Henry Cow)
19. Kraftwerk - Radio-Activity (Radio-Aktivität)
20. Tangerine Dream - Rubycon

From the poll, I will go with Hawkwind now even if Wish You Were Here is currently higher on my list (right before that I put Hawkwind higher, whatever, both are great) I can't really decide on an order for it, too much I love from the period. I got much more into that band recently and that is an excellent album. Libra and Odyssey are some other particular favourites. I was expecting to see Dzyan but very happy with what I voted for.

^ Actually thoiught that might be the case. PA says 1974 and I may well have the date of first release wrong. Discogs agrees with you and Prog Archives.

I went with Soft Machine-Bundles ; also, Eno- Another Green World ; Hatfield and the North; Steve Hillage -Fish Rising. 

Wish You Were Here, followed by "not on the list" Physical Graffiti and Minstrel in the Gallery.
