After I carefully listened to the top 15, I didn't know where to go from there. I had to scavenge these forums for recommendations simply because they are a bit scarce unless you do some searching. From your point, I'd recommend Graveland's Thousand Swords, Averse Sefira's Tetragrammatical Astygmata, and Dimmu Borgir's Stormblast. Recommending any Dimmu Borgir is probably frowned upon I'm sure, but Stormblast is a good album and it deserves a attention. If you don't mind death metal, try Gorgut's Obscura and At The Gate's The Red in the Sky is ours.
As for relating to Immortal's sound/feel, I don't think any bands actually come to close it. But if you ignore the aesthetics of Immortal's sound, to me it's just like any other top-tier black metal album.
