I know there's a ton of Post-Metal or Instru"metal", or whatever you want to call it, bands out there right now. A lot of it sounds pretty much the same and there's all kinds of blogs out there dedicated to this genre. Two of these bands really seem to stand out amongst the rest to me for some reason. Both Omega Massif and Mills Of God are from Germany and are amongst my favorites that I've heard recently. Slow, sludgy and super heavy.
