I always loved ATMOSPHERIC albums; my all-time favorite one, because I believe almost nobody can make a more modern atmospheric album like that, is definitely david helpling - sleeping on the edge of the world.
it is easy for me to produce a list of albums i consider EXTREMELY atmospheric:
prog:
1-pink floyd - a momentary lapse of reason
2-vangelis - mask
3-eddie jobson - theme of secrets
4-pink floyd - the division bell
5-IQ - subterranea
6-collage - moonshine
non prog:
1-Jon Jenkins - flow
2-David helpling - sleeping on the edge of the world
3-michael stearns - planetary unfolding
4-mark isham - castalia
5-yanni - keys to imagination
6- patrick o'hearn - rivers gonna rise
I'm sure I forget many ones!!
