The Verve - A Storm In Heaven
Not ambient but I love it.
A big favorite of mine. Too bad they never made another album quite like it.
This album has a somewhat similar vibe:
They also never made one as consistent either. I love the style they had on A Northern Soul but there's some tracks that drag it down a bit. I actually don't mind Urban Hymns as a pop album but it's too long for its own good.
Thanks for that recommendation.
Also, you should check out Vidna Obmana's collaborations with Steve Roach if you haven't already. You really can't go wrong with any of them. Well Of Souls is a good place to start. The textures are amazing.
