I think Blackbraid is perfectly fine. It's nothing special, but neither are the never-ending wave of one-man, bedroom, raw black metal projects. And black metal fans seem to have no problem gobbling up that tsunami of mediocrity.
As for it getting a big push because the man behind it is Native American? I dunno, could be. I find it to be a breath of fresh air, personally. Something different from yet another Scandinavian or eastern European larper screaming about "muh pagan/viking heritage".
