I haven't heard much good BM from Canada, except Blasphemy.
They've produced some great DSBM, like Gris and Sombres Forets.
What's the critique of Negative Plane on this board? A band from New York, who have 2 albums out. From 2006 "Et In Saecula Saeculorum" and from 2011 "Stained Glass Revelations." I favor the debut, but SGR is fuckin' excellent. Probably, the most unique BM band I've heard in a long while. Has a thrash/death style composition. You can sense the decrepit, dank and dark place of Castles or Cathedrals. Tremendous atmosphere. Curious as to what others think about this band.
I think they're great, I prefer Et In Saecula... to Stained Glass Revelations, but both display great musicianship and a fantastic dark atmosphere. Really looking forward to seeing them in London in August.
