I own a ton of albums, unfortunately I can't think of them all of the top of my head, and I need to be at home to read them all off.
In terms of doom DVDs, I've only got:
1. Black Sabbath - Never Say Die
2. Black Sabbath - The Black Sabbath Story Vol. 1
3. Black Sabbath - The Black Sabbath Story Vol. 2
4. Black Sabbath - The Last Supper
5. Black Sabbath - Random Mexican DVD containing cut items from Vol. 2 DVD
6. Candlemass - 20th Anniversary Show
7. Candlemass - The Curse of Candlemass
And the CDs... I own every Black Sabbath, Dio, and Iommi CD... Cathedral's The Ethereal Mirror... Some Monster Magnet... And I can't remember the rest.
