This band is brilliant. The doom tag is a bit of a misnomer these days. Power doom absolutely fits, though. It's a term that's been used for a long time with bands like Solitude Aeturnus, and it fits here, I think. Not a genre, though, and we sure as hell don't need another.
The debut EP is where the doom label really comes from. It's out of print now, but I can upload it if anyone is interested.
