Wow, this thread turned out way better than I expected it to. Some great recommendations to search for. I much more enjoy searching in record stores than ordering on line. Many mentioned, I already have. I think of those listed that I don't have, I am going to start looking for Renaissance, Porcupine Tree, The Pineapple Thief, Godley & Creme, and the Marilyn Manson suggestions. They might be obtainable locally. Thanks again for the great posts.
Best progressive rock album side
My intent is to seek albums which I may not own from the recommendations of you all. I ranked best sides of progressive rock albums on vinyl that I own and came up with the following list. I don't want it to undermine anything else that an artist has created. I love it all but as far as start to finish on one side this is what I came up with.
#1: Supper's Ready
#2: Terrapin Station
#3: Atom Heart Mother
#4 The Court of the King Crimson
#5 Echoes
Of course there are many more. Some may not be complete sides like Atom Heart Mother but the intent of the artisan was to make it a complete side. I had a very hard time deciding between #1 and #2. Both are very worthy in my mind.
