FYI they’re still technically called “Ghost.” The B.C. part is only used in North America.
If you haven’t heard them yet, make sure you listen to Church of Death by Vanhelgd and Tenebrous Towers by Desolate Shrine. Vanhelgd is Swedish-style death metal with some early At the Gates flair (think Gardens of Grief/TRitSiO), Desolate Shrine is Finnish death metal with some black metal and a small touch of Bolt Thrower added in.
They’re my two favorite death metal albums of the year, with Doom of the Occult not far behind.
