Yeah, they were one of the bands that opened when I saw Sunn O))) over the summer, so that's how I was exposed to them. In fact they were the only opening band that I enjoyed. Then a friend of mind kept raving about the new album and continually prodded me to check it out, so finally I gave in.
I have yet to listen to Diadem of 12 Stars, but if it's as good as or better than Two Hunters I'll have to check it out.
