This band, like Cradle of Filth, seems to divide opinion wherever you go. Personally, I think Dimmu Borgir are excellent. No, they're not the most kvlt band in the world ever, but I really don't think that's what they set out to do. They create good, symphonic Black Metal. Like any band, some albums are better than others.
I saw that someone mentioned Chrome Division somewhere in this thread - Brilliant band! If you're looking for a bit of r'n'r then look no further. Although, I will say that I preferred the first album compared to the second one. Both are worth a listen though.
