I saw them do a few songs at a festival once, they were okay from what I heard. They've been around 20-ish years so they have several albums, I'm sure at least some of it is good. I don't really care for the aesthetics, to me the singer looks like a combination of a shitty version of The Crow and the demon from Death Note.
They also remind me of this band, which I prefer. I like the power metal/evil church combo. It's like Ghost, but not shitty.
