In my opinion, there are lots of bands that are NS that are overlooked. But that's usually due to a stereotype portrayed by many bands in terms of sound/lyrics. Its overlooked where I live, because I reside in Israel. I got flack from admitting so one time though, so I just keep my mouth shut.
Also the current "Orthodox Black Metal" scene. I mean, sure, the image is stupid and over the top and I can understand that. But I think there are quite a few gems in this label.
@Donnie,
I can agree
