My logic isn't that because scene kiRAB like it it will suck. I'll give it an honest listen, but based on the average person who seems to like it I'm not expecting much. I also agree that basing your opinions off of other people's opinions is durab, and disingenuous at best.
It isn't really an age thing. Summoning date back pretty far and they're really solid. Rotting Christ would be another example of a black metal band who's been around for years and has managed to release a lot of good material. Just for the most part I can't get into raw black metal for some reason. It just feels lacking in something.
Is an essential part of every metal collection, although I wouldn't recommend them to someone just getting into metal. They're a bit rough around the edges and artsy.
