So, I saw this ranking on Rolling Stone magazine of the 50 greatest prog albums. I then quickly remembered why we pay no attention to RS's opinion. I therefore decided to make my own listing of the 30 greatest prog albums. Quick note, I really don't want to offend anyone if forget any of your favorites, like Rolling Stone did to me.

30. Meddle- Pink Floyd
29. A New World Record- ELO
28. Permanent Waves- Rush
27. Hemispheres- Rush
26. Brain Salad Surgery- ELP
25. War Child- Jethro Tull
24. Trespass- Genesis
23. Emerson Lake, and Palmer- ELP
22. Procol Harum- Procol Harum
21. A Question of Balance- The Moody Blues
20. For the Power and the Glory- Gentle Giant
19. Electric Light Orchestra- ELO
18. The Yes Album- Yes
17. A Salty Dog- Procol Harum
16. Nursery Cryme -Genesis (Also my personal favorite on this list)
15. Octopus-Gentle Giant
14. Eldorado- ELO
13. Lamb Lies Down on Broadway- Genesis
12. Caress of Steel- Rush
11. Tarkus- ELP
10. Fragile- Yes
9. Songs from the Wood-Jethro Tull
8. Fly By Night- Rush
7. 2112- Rush
6. Selling England by the Pound- Genesis
5. Close to the Edge- Yes
4. Aqualung- Jethro Tull
3. Dark Side of the Moon- Pink Floyd
2. Thick as a Brick-Jethro Tull
1. Foxtrot-Genesis
Honorable Mention- Quadrophenia-The Who, not included only because it isn't your typical prog album.
I only didn't include King Crimson because I've never listened to any albums of theirs all the way through, so therefore I don't feel I can make an accurate judgement. I'm a failure!
I literally feel like I forgot like twenty million perfect albums, but I tried.
