Shadowplay mentioned Pharaoh Overlord, I think them and Circle are insanely good, they have just the right amount of chug vs motorik mix, and also a sense of humour, they don't take themselves too seriously. Saying this they make some of the most amazing drone and ambient field recording stuff, and often tip over into primal Progg, akin to blissful Trad Gras Och Stenar commune rock.
I think this track "Dark Star" is great, almost as if Can were a metal band, I love the idea of taking a really heavy riff and repeating it robotically like this and pushing the emphasis around.
Pharaoh Overlord - Dark Star
Love this track from Sweden's Horizont too, more of a classic rock sound but still really heavy:
Horizont - Visa Vagen
ST Mikael's vocals are an acquired taste, but some incredible fuzz rock to be found in these albums. Original Dungen drummer Fredrik Björling (he of the "Panda" drum intro!) and Reine Fiske on bass too.
