Another worthy hard rock album from 1987:
Appetite, Hysteria, New Jersey and Whitesnake were MONSTER sellers. I think they're all at least 7x platinum, and Appetite and Hysteria are probably double that. The Europe album isn't anywhere near that level (although it did go platinum).
Aerosmith's Permanent Vacation is probably the only other hard rock/metal album from those years on the same level as Appetite, etc. (I'm talking sales only). Maybe Motley Crue's Girls x3 and Poison's Open Up and Say...Ahh!
But for my money, the best albums of those two years are
Helloween - Keeper of the Seven Keys: Part 1 and Part 2
Queensryche - Operation: Mindcrime
Triumph - Surveillance
Fates Warning - No Exit
Metallica - And Justice for All
Iron Maiden - Seventh Son of a Seventh Son
Judas Priest - Ram It Down
My dislike of GnR has been well-chronicled here.
I don't HATE them but I think I listened to them too late. Shoulda been there type thing.
I like some songs but I tried to listen to AFD recently and did not like it at all.
Maybe...I was there. Didn't help.
IMO Metallica (1991) is far superior.
My fat cat whining at my bedroom door at 5:30 a.m. because he wants to be fed is far superior.
