Cold post-rock

hey guys, i'm seeking some post-rock with kinda cold atmosphere. it would be post-rock or ambient in general, but with variative infulences whatever it can be post-metal, sludge, black metal, trip-hop ect.
as my favourite for example such track as MGR – In Conjunction, ThisQuietArmy – The Pacific Theater, Harvestman – The Burning of Tara, and so one.
