Rock Albums With the Most Unique Vocals

Some bands have/had singers with the most unique vocals. And some albums showcase those one of a kind vocals at their best. These are the albums with the best of those unique vocals.
The Top Ten
1 Houses of the Holy - Led Zeppelin
2 Live! Bootleg - Aerosmith

The thing that sets this apart from every other album is that this was done live. No extra takes on vocals. Everything was done on the first attempt and it was done with crazy precision for how intense each vocal had to be.

3 Sad Wings of Destiny - Judas Priest
4 Paranoid - Black Sabbath
5 Highway To Hell - AC/DC
6 2112 - Rush
7 Close to the Edge - Yes

I respect Yes but I have a beef with Jon Anderson's voice.

8 Fire of Unknown Origin - Blue Oyster Cult
9 Revolver - The Beatles
10 A Night at the Opera - Queen
The Contenders
11 Frizzle Fry - Primus

Sounds like nothing else, really.
