"Dark" Albums

I have seen lots of reviews where they say "This is the bands dark or black album"

In the case of Kansas, it was Masque with songs like Child of Innocence (When listening to this one thinks of the Grim Reaper) and The Pinnacle. With Dream Theater it was Train of Thought with disturbing songs like Honour Thy Father and In the name of God. Dark as in serious and disturbing to the listener.

What would you say are some of the dark albums  for other big progressive bands?

Anything by Univers Zero or Shub-Niggurath

Pain of Salvation (any, esp. One Hour By the Concrete Lake and TPE)

Satellite: Evening Games (not depressing or heavy, just a bit dark, melancholic and pleasant)

Arena: The Visitor, Immortal? (though I've only listened tho them once, so take that as you will)

Bj-1 wrote: Van Der Graaf Generator - H to He and Pawn Hearts Genesis - The Lamb Lies Down on Broadway King Crimson - Islands, Starless and Bible Black Pink Floyd - A Saucerful of Secrets Jean-Michel Jarre - Zoolook Supertramp - Supertramp Gentle Giant - Acquiring The Taste Soft Machine - Fourth, Fifth Dream Theater - When Dream & Day Unite, Awake Shadow Gallery - Shadow Gallery Yes - The YES Album, Tales From Topographic Oceans

The Yes Album a Dark album??? With "I've seen all good people" and "Yours is no disgrace"??

Tales DARK??

I don't see that for me these two albums (together with the rest of the Yes catalogue except maybe  Relayer and then specially for the beginning of the Gates of Delirium, allthough the end "Soon" sooghts that) are happy and very LIGHT (not musically, but opposed to "dark") music.

Dark music to me is like schizophrenia, melancholy, other forms of mental or social disorder.

Dark albums are many

e.g.

Metallica -  Ride the Lightning

VdGG - Still Life

Pink Floyd - Dark Side Of The Moon

Riverside - Out of Myself

just to name o few
