My one problem with the community of people who listen to this type of music and will have listened to a lot of the stuff that came out of Scandinavia during the 90's, like early Dimmu and Satyricon, Behmoth and so forth complaining when the bands try to move on and evolve their sound.
I remember talking to a guy who claimed to be "a huge Dimmu fan" but hadn't liked anything they'd released since Stormblast. He claimed that the band sold out and weren't Black metal anymore. To me this is just bands evolving and maturing. I feel it's natural for bands to grow and to expect them to continue pumping out the same sound is just moronic.
