Bergraven turns the traditional blast-and-flay aesthetic of "frost bitten grimness" on its ear and comes at you with sweeping riff dirges, winding cinematic passages, melodic guitar interludes, tortured-yet-vaguely authoritarian and Germanic vocal overtones and - get this - ambient pedal steel excursions. All of which is enough to make your head spin, especially if you're down with weirdness.
