Insomnium, espeically on their second album Since The Day It All Came Down.
Woods Of Ypres, especially on their debut full album Pursuit Of The Sun & Allure Of The Earth.
Subterranean Masquerade, check out their EP Temporary Psychotic State.
Orphaned Land use them a lot too, but also a lot of other shit as well.

@Hemlok:
Exquisite mentions, I already have some of their albums
(But Dornenreich are from Austria)
That Cathis Ord band was pretty cool from what I heard on their myspace but I really have no idea how to obtain their stuff if you didn't order their demo when that guy posted it.
