Enjoyed the topic tonight. Here are my takes on those 4 albums:
Yes - Tormato: Never one of my top-shelf Yes albums but I enjoy it well enough that it gets a spin every couple of years (6/10)
Rush - Caress Of Steel: The first Rush studio album I bought and I really enjoy most of it. I agree that The Fountain Of Lamneth is a bit choppy, but it also has a lot of great musical ideas. Bastille Day is a fantastic opening track. (7/10)
King Crimson - Islands: This is prime KC in my book and one of the more immersive listens for me from the early KC catalog. I still play it quite regularly. (9/10)
Gentle Giant - Civilian: It is a product of its time and I enjoy it for what it is. Of the four albums under discussion tonight, though, I would rank it at the bottom. (5/10)
