I don't know - something about the same tempo being utilized in almost every song, along with the same time signature, along with similar sounding melodic lines throughout much of it (to my admittedly layman understanding of melody) all adds up to an album which just seems to churn out the same song over and over.
Maybe I just haven't spent enough time with it. Maybe I'm just a big fucking faggot. I'll figure it out, but as regards later Graveland, I really can't get into it in the same way that I get into early Graveland. That said, I'm not even all that huge of a "fan" of Graveland to begin with. I just have a very lukewarm response even to the better compositions of Darken's.
Man, I would fucking love it if he lost the drumming. That's the only thing that trips Lord Wind up, although I am able to tune that aspect out.
