Graveland

The Celtic Winter is in the style of early Emperor. Though I prefer it to that band, it's not one of the best Graveland albums.

Carpathian Wolves is excellent, perhaps the production has thrown you off, but there's a heavy folk influence on that album. Thousand Swords is Darken's best effort, one of the top 5 metal albums to be released.

"Forgotten Songs" by Lord Wind is "Thousand Swords" but not metal, highest recommendation.
