i am searching for bands like which sounds like that:
Carpathian Forest - Cold comfort (http://www.youtube.com/watch?v=M_mtzJqI ... re=related)
i like the crushing voals slow paced music with the Saxophone?

and i am also searching for very slow Black Metal like FuneralDoom but not Depressive/Suicide BM

mournful congregation is good for slow doomy music also so is disembowelment

Bm with jazz elements? Pure heresy.

Nachtmystium - "Seasick Part II: Oceanborne" was the first to come in mind.

Try Nortt - Ligfærd, pure nihilistic funeral doom/black metal.

Absolutely not. Klabautamann's latest release "Merkur" should be what you're looking for. Maybe not slow, but definitely aggressive. The jazz should be obvious but it comes off very nicely!

Holy Fuck!!!! That's amazing!

I second the diSEMBOWELMENT recommendation. I can hear a very prominent black metal influence in their later work, even though the gist of the music is doom/death with jazz influences.

Check out Ved Buens Ende, very jazzy black metal, and one of the earliest examples of such a band.

And while you're there, you may as well go onto Virus, the followup band. It's a bit less "black" than VBE, but if you like the surreal sort of avant-garde stuff going on there, you'll probably like Virus.

There's also Oranssi Pazuzu, who throw in some psychedelic influences alongside some jazzy ones in their black metal. Good stuff there.

Fleurety's Department of Apocalyptic Affairs, though I am not sure if it will satisfy you since it is more a jazz metal, than jazz black metal. However, the roots of this band are clearly in black metal.

maybe have a try with DEVAR:
