I started to comment on it, but it is to much to say.
But in that album you hear the voices trapped in sorrow and isolation.
One small example.
If you should go skating
On the thin ice of modern life
Dragging behind you the silent reproach
Of a million tear-stained eyes
Don't be surprised when a crack in the ice
Appears under your feet.
You slip out of your depth and out of your mind
With your fear flowing out behind you
As you claw the thin ice.on thin ice, dragging, the voices crying (and they can break a mind)
down into the water, then the insanity, and fear, as he tries to get out of the water.
Each brick in the wall, is his inability to break out of the shadows, back into the light, which includes isolation from other people, for the depth is isolation. and each attempt makes the wall look higher.
There is a really old two sided conflict, and I think that pleading came from, the bad worst side.
Just reading the lyrics tears the mind apart terribly.
Here is a song(christian) that is a better way out(or was for me) from behind the wall.
