Best Metal Vinyl Album

Content quality or sound quality?
Content for me would be
Black Sabath debute
Metallica Kill em All
I have a hard time narrowing a final pick.

Audio quality isnt really an issue, crap production can still make my feet tap just as Patricia Barber can put me in coma.

If we're talking about content quality then here's my top 3:

Slayer-Reign in blood
Metallica-Ride the lightning
Voivod-Nothingface

Good question:

Sound qaulity would be:
Black Sabath- debut at 180g
Mastodon -Hunter 45rpm
Deftones-White Pony

Content quality would be:
Testament-Dark Roots
Metallica-Ride the Lightning
Slayer-Reign of Blood

Just received the 180g Ozzy-blizzard and Diary. Wow, sound qaulity is great. Great to see a few more Metal Heads on here.

Judas Priest - Stained cLass
Accept - Restless and wild
Mustasch - Ratsafari
