Disclaimer
These are my favourite progressive rock
albums. Again I had to set some ground rules
so that things do not become chaotic.

(1) For me the first Progressive Rock
album is King Crimson's first album released
on the 10th of October 1969. Anything
before that is not taken into consideration.
(2) The Progressive Metal genre is going to
be covered in a separate list, so no albums
from that genre were considered.
(3) The long time period covered made me
change my usual 25 choices to 40. Also there
are 2 albums per artist with two notable - and
I think justifiable - exceptions.

Feel free to comment!

P.S. Albums are in alphabetical order
