Drudkh is my favourite thus far.
I liked Devins solo record too, I thought it explored some new ground, which I liked.
I think the Acoustic Verses by Green Carnation was a 2006 release too, so it's definately up there.
Ihsahns The Adversary was a great record too.
Decapitated released an onslaught with Organic Hallucinosis, and they were intense when I saw them in may.
Witchery's Don't Fear the Reaper kicked a whole bunch of ass, I thought.
The new Cannibal Corpse (Imaginatively titled KILL) was ace.
Celtic Frost, Sadus, Sodom, Vader, Katatonia and Amon Amarth get honourable mentions.
Non-metal-wise, I thought the Flaming Lips, The Kooks, The Futureheads, David Gilmour, Eileen Rose, Dirty Pretty Things, Muse and the Mars Volta released good records - Especially the ever beautiful and entertaining Eileen Rose.
