Most depressing metal album

Neurosis - Through Silver in Blood

The Eye of Every Storm, too...I mean, just listen to the first few minutes. Given To The Rising is pretty hopeless too. Neurosis own.
 
Funeral--Tragedies and Mournful Congregation--The Dawning Of Mournful Hymns. These 2 albums make BMD-Katatonia and any Anathema sound like Animal Collective. If you can get through "Tragedies" in one full sitting, you are beyond depressed man. Your ready for the bridge or cliff.
