Metal albums that are "MUST HAVES"

megadeth - risk
metallica - saint anger
judas priest - turbo
anything trivium or machine head
newer kovenant, dimmu borgir, opeth, in flames, amorphis, katatonia, paradise lost, cradle of filth, def leppard, and arch enemy.

All are future inductees to the museum of modern art

That was a lot of effort for a troll post.

edit: besides, you forgot Nightwish, DragonForce, Rammstein, and System of a Down
 
Unexpect - In a Flesh Aquarium - THE BEST avant garde album I've heard in years.
Suspyre - A Great Divide - Awesome prog album
Equilibrium - Turis Fratyr - My alltime favorite Folk Metal album.
Behold... The Arctopus - Nano-Nucleonic Cyborg Summoning - Relatively new instrumental avant garde band i recently came across. I love it, but its certainly not for everyone.
 
if you're looking to get into the extreme doom all these albums are must haves

Asunder - Works Will Come Undone
Disembowelment - Transcendence Into The Peripheral
Esoteric - The Pernicious Enigma
Evoken - Embrace the Emptyness
Funeral - Tragedies
Katatonia - Dance of December Souls
Morgion - Solinari
Mournful Congregation - The Monad Of Creation
Skepticism - Stormcrowfleet
Thergothon - Stream From The Heavens
Winter - Into Darkness
Worship - Last Cd Before Doomsday

Good post, but Farmakon is the better Skepticism album imo.
 
Garden Of Shadows - Oracle Moon. Why does nobody seem to know about this?! If you want decent death metal, get this, it kicks ass.
Also get Agalloch's second album, "The Mantle" if you haven't already, tis amazing.
 
Morbid Angel- Domination
Asphyx- The Rack
Pestilence- Consuming Impulse
Candlemass- Nightfall
Death- Symbolic

a few classics you should at least listen to
