Danzig 4p is currently my #1 album ever. It used to trade places with ÆNIMA for the 1 and 2 slots in my head, but honestly Tool's '90s stuff just sounds so... '90s to me a lot of the time. I spun Danzig 4p like 20 times just a few weeks ago, just as powerful as ever.
The mood. It's just so god damn dark and black. Not evil or devil-like or depraved or anything like his other stuff. Just... black. It's like the audio equivalent of The Nothing from the Neverending Story. Not in any tragic way, just a lacking absence of all. Something like that.
i like 4, its the darkest of 1-4, but that also makes it a little less varied, and less memorable riffs i think. probably 4th out of 4 for me but they're real close.
