Why do we talk about "them" liking or not liking the new material? It's supposed to be 95% Alexi's vision. How many people have the same taste in music? Even fans of melodic metal rip each others organs out discussing whether Bodom is the best ever or the gayest shit ever, or any other such band. What likeliness is there for all the five members of the band to think the same of the new material? Very minimal. If they all like it, that means they all had their own input on it, which would quarantee the album to suck. As long as Alexi adores it to death, is all that matters.
I realize it's easy for Alexi to write this kind of songs, but it's very very difficult even for him to give the songs that final edge of artistic vision to make them epic. So I figure he must stay true to himself and write whatever is pure to him. If he attempted to write something like the old COB, it may not be spontaneous so it could be hard to make it sound very good.
It's funny how everytime a new album is out they talk dispisingly about the "old-school neo-classical wankery COB", refusing to admit there was something special about it too. Then when a new album is in production, they suddenly talk sweetly about it having elements of the old COB, yet no neo-classical wankery... I suppose it's like every single melody is supposed to be old COB and every single riff is supposed to be new COB.
