I usually have no problem with weird voices. Sure, there’s the odd one that rubs me the wrong way but, more often than not, I can ignore or even enjoy a weird voice when I hear it if I like everything else about the music (and especially if that voice is talented).
The problem for me with black metal is that it generally always sounds the same. The black metal bands I’ve heard just do black metal (or melodic black metal, or whatever) and that’s that. They are content to release 50-60 minute onslaughts of one sound and leave it that.
As far as I know, this is the first “melodic” black metal album (it may not be, I’m not a genre obsessive). It’s basically black metal with cheesy keyboards.
