Well I don't know if they'd be what you're looking for but I'll drop a few names off the top of my head here.
Fen - they play atmospheric BM with post-rock elements with lyrics more in the nature vein.

Darkspace - atmospheric BM again, this time though with more ambient elements and spacey themes. 

Hail Spirit Noir - these guys mix BM with psychedelic rock. They have some satanism in their themes though I believe. But musically they certainly fit the bill of 'interesting' in my mind. 

Progenie Terrestre Pura - more ABM with ambient leanings and sci-fi themes. They also have a pure ambient/electronic EP.

Winterhorde - A progressive BM band. I highly recommend their album Underwatermoon. Very adventurous stuff. 

I'll also second Myrkur, but I don't think she's reached her full potential yet after just one EP. Definitely worth a listen though.
