Black Metal.

So V5, I did like you and downloaded the Naxzul album, but unlike you, I can't see myself buying. It's not very good, perhaps bordering on bad. The atmosphere and ambience is great, but the music is just so riffless. Obviously keyboard driven music but even the keys don't do much other than sustain one chord per bar most of the time.
 
uhh sort of. not nearly as ambient or "space-y", but really awesome stuff nonetheless...you should look into Paysage if you're a fan of Darkspace
