Black Metal.


His formula is getting old. If he's going to make another album he should wait a long time so he can hone his material and make it really good. Most of the later Graveland albums are merely competent imo. But if you enjoy what he does, then more power to you.
 
I love old Arckanum and the first Sacramentum album. Those are probably my favorites. I don't like the generic blasturbation garbage like most Marduk, Funeral Mist, the new Nefandus and Ofermod albums and just about all the other more modern aggressive Swedish religious Satanic black metal bands.
