Hmm, how about some Dutch death/doom in the form of Asphyx and Hail of Bullets? Both are rather similar musically, containing several shared members and near-identical writing styles. Massively heavier-than-a-bulldozer walls of guitar, comprising tremolo riffage and slower groove-based riffs, a strong thick production and Martin van Drunen's trademark vocals, which sound like his vocal chords are being put to their limits, conjuring the visions of soldiers screaming and dying in trenches. It's all really perfect stuff, and some of my favourite death metal.
Edit: There's also slower, melodic and somewhat "epic" songs as well. Which is actually some of the best material.
