I still think taht morningrise is the most depressing of them all don't know why, maybe it has to do with what mood i was in when i bought it.
blackwater park and still life are sometimes a little bit happy, when you only listen to the music and not in still life's case read the story(which is really sad).
I don't know that is just how I feel.
but I will have to agree that deliverance and MAYH is also kinda depressive.
Sometimes Orchid also.
I think MAYH is the most dark, but the album has a lot of beutifal acoustic duet passages that help lighten it up.
I found it is kind of like a roller coaster ride and that is why I like it the best because not a lot of albums can do that.
Deliverance feels kind of uplifting.. in a dark way, but it's not my first pick. Probably Orchid, it just has this dark tension through the whole thing. MAYH and Morningrise are close, but they're a little above.
