Albums that you consider to be a band's best work...

I don't generally read popularity contests from fans of bands, so I don't really know what people rank albums as, but some of mine would be:

Dream Theater - Awake
Metallica - Kill 'Em All
Angra - Aurora Consurgens
Evergrey - The Inner Circle

I feel it's necessary to requalify that short list by saying that I know relatively few metalheads, and I don't get much time to pow around the internets to hang out with many there.
 
Gamma Ray - Majesty
Love this album...still have no idea why it gets so much dislike with songs like My Temple.
 
Good call whoever picked Bruce Dickinson "Skunkworks" and Black Sabbath "Eternal Idol"...those are two of my desert island albums!

Bruce Dickinson - Skunkworks
Iron Maiden - Dance of Death or AMOLAD
Uriah Heep - Wake the Sleeper
Black Sabbath - Eternal Idol
In Flames - Whoracle
Blaze - Blood & Belief
Ozzy - The Ultimate Sin
Dio - Master of the Moon
Nocturnal Rites - Tales of Mystery and Imagination
Deep Purple - Purpendicular
Motorhead - Bastards
Saxon - Unleash the Beast
