Twelve bands that did not disappoint this year, no particular order:

Panopticon - Collapse + their two splits
The Chasm - Farseeing the Paranormal Abysm
Blut aus Nord - Memoria Vetusta II: Dialogue with the Stars
Magma - Ëmëhntëhtt-Ré
Mastodon - Crack the Skye
Isis - Wavering Radiant
Drudkh - Microcosmos
Krallice - Dimensional Bleedthrough
Finsterforst - ...zum Tode hin
Between the Buried and Me - The Great Misdirect
Cobalt - Gin
maudlin of the Well - Part the Second

There's still a lot I haven't sorted through yet so my list may end up changing (Converge probably belongs in the company of the above, but I need to make certain that it withstands repeated listening). There are plenty of other bands who deserve honourable mentions as well (Wolves in the Throne Room would have to be near the top of that list), but I can't be arsed listing them all.
