Dark Ambient Sketch #1

I don't know how you guys describe "Dark ambient", but to me, it's a cold and sad genre. I recorded this just this afternoon :

I know it's not that good, because everything is improvised, and I did not spend so much time on mixing and mastering.

I'm amazed that in some of this actual styles tension-relief is made by less or more distontion.

You improvisation is nice and it has the feeling of "ambient", something surrounding us.
