It will take me a couple of days to listen through metal so:)

Very close to metal: Mariner album by Cult of Luna 🔥

Post-metally stuff:

Isis (as I've mentioned): In Fiction, Garden of Light. Metalheads allegedly prefer Oceanic album; melodic post-metal with vocals, outros are simply beautiful.

Cloudkicker: Dysphoria, We're goin'in - completely instrumental, more energetic.

Russian circles: the whole Station album, Mota, Mladek - amazing drums and outros are out of this world.

Lighter post-rock:

God is an astronaut: Epitaph, All is Violent all is bright post-rock with heavy electronic influence

Toundra: III very nice song
