Exactly I hated cathedral although I thought candlemass was okay, i think those are generally considered "Doom metal".
I'll have to try those other two you mentioned but just so you know heroin and crack aren't psychedelics. Psychedelics are things like mushrooms, lsd mescaline etc. I suppose anything can be considered psychedelic in one way or another but smoking crack is so much different than doing psychedelics and I imagine the music that would be enjoyable would be alot different
have you listened to neurosis carnivore is god?
