well i love emperor because of that fact that they dont sound like typical black metal (cuz i dont like black metal), even the first albums which are bm (but special), the last two arent really.
now that argument about 15 old with corpsepaint ....just stupid. do you really now anything about music? listen to a song from prometheus and tell me that sounds appelling and catchy, and if emperor sounds trendy to you , you better clean your ears. emperor had the balls to change and still keep the quality, actually if you look at prometheus, its the most complex album they have done. (and they dont sound like cradle or dimmu at all) . stop being trendy and bashing them, and actually listen to a album of theirs, and maybe you will learn something.
the harmonic , counterpointed compositions are notable.
