Is there any one metal album that we can all agree is an absolute classic?

Holy Wars, Five Magicks, and Lucretia (DAT groove) are the best.

Also, the guitar tone is awesome and a large part of what made me like it so easily as a kid. So processed and synthetic sounding it could almost fit a vidya soundtrack. Love it, perfect for the hyper-energy hyper-wank mood of the album.
 
He doesn't have a consistent album to his name. The closest he ever got was with Youthanasia and Cryptic Writings.
 
How about:

Rainbow - Rising
Dio - Holy Diver
Motörhead - Overkill
Ozzy - Blizzard of Ozz
Death - Scream Bloody Gore

Absolute classics imo

Rising has one classic song and other very good ones, not really strong enough as a full album though. Holy Diver is definitely close to the pinnacle of streamlined metal songwriting. Motorhead is a classic band with no full classic albums imo. Blizzard of Ozz is great, not quite classic. Scream Bloody Gore has too many just-good songs.
 
Symbolic is the best of progish-era Death, but also lacks great highs, and is just a refinement on the previous too albums anyways. Coma of Souls is so horrible.
 
How about:

Rainbow - Rising
Dio - Holy Diver
Motörhead - Overkill
Ozzy - Blizzard of Ozz
Death - Scream Bloody Gore

Absolute classics imo

Only Holy Diver from that list is a true classic. Never been able to get into Rising, but probably owe it another shot. Blizzard of Ozz, SBG, and Overkill are very good, but not great.
