As previously mentioned, Wolves in the Throne Room and Weakling are both excellent examples of sweeping, epic music, but both are much more in the black metal vein. Deafheaven - Roads to Judah is another black metal album worth checking out. Ihsahn has been mentioned, but why not back up a step and try Emperor - Anthems to the Welkin at Dusk? Also in this vein, Windir has some amazing albums, especially Arntor and 1184. For something even more grim, black and frigid, there's Coldworld - Melancholie².posted by fiercecupcake at 1:40 PM on September 3, 2011
For bands that are much prettier yet still powerful, the previously mentioned Alcest fits the bill, and so does Les Discrets. Mastodon - Leviathan, Wintersun's self-titled album and Machine Head - The Blackening aren't black or folk metal whatsoever, but all are stellar.
If you like doom, there's always Candlemass - Tales of Creation. Summoning might be the only example of Tolkien metal that I know of, and the albums Oath Bound and Dol Goldur are both very powerful. And if you like the the previously mentioned Sunn O))) and Nadja, you could check out Asva - What You Don't Know is Frontier.
