Black Metal.

It's fairly similar, but a bit more leaning toward the Hammerheart style. Frankly, it's a toss up for me as to which is better.
 
I'd say Immortal Pride is just as good. Stylistically it's a mixture of Thousand Swords and the newer, Hammerheart influenced material. Bear in mind that it only actually has two Metal songs, both of which are extremely long, but extremely repetitive they are not. It'd be in my top three Graveland albums after Thousand Swords and Following the Voice of Blood.

Edit: Beaten to it.
 
I found a couple more black metal bands I like, Nargaroth and Horna. I also heard some ...And Oceans but the riffs didn't seem as good as their symphonics and riffs are number 1 priority.
