I looked at five different lists of top 100 classic rock albums as reference* to see what came out as the most popular. I compiled the list below from albums that showed three or more times on the reference lists I used. As would be expected there are some surprising omissions and some unexpected inclusions.
In total there were 284 different albums listed and 160 different artists overall. Surprisingly no showing of Iron Maiden in the final list with only two of their albums getting an mention at all, Number of the Beast and 7th Son of a 7th Son which both got two listings. I would also have expected more showings from Black Sabbath and Deep Purple but both bands only have one album to show in the Top 70.
Some surprise showings (well to me anyway) were Pulp, Blur, LCD Soundsystem, Daft Punk and Joni Mitchell,not quite sure how these qualify for Classic Rock but there you go.
The top six albums on the list had a mention in all the references I used, the next 30 had four mentions and the rest had three. Also worth pointing out 35 of these albums were released in the 70's and 27 of them also featured in my Best 70's Classic Rock Album list so a good amount of consistency there really.
Special mention has to be made for The Who, whose album Who's Next topped this list and Quadrophenia which topped the Classic Rock Albums of the 70' which I did.
I only have nineteen of these albums on vinyl ( more if you count CD copies) so I need to visit more second hand vinyl shops.
