Lamb of God's 'Wrath' is a runaway winner for me. This band deserve to go down as genuine metal legends in my book, and never seem to put a foot or riff wrong.
Other worthy contenders:
Baroness - Blue Record
Fu Manchu - Signs Of Infinite Power
Mastodon - Crack The Skye
Megadeth - Endgame
Hospital Of Death - Surge Kill Steal
Other contenders which will be worthy when I get around to buying them:
Invasion - The Master Alchemist
Angel House - The Gun, The Love and The Cross
Wolfmother - Cosmic Egg
Russian Circles - Geneva
Best Album of the Year by a bunch of my highly talented (and equally retarded!) mates:
Finish Him! - An Audience With...
I slept through Lamb Of God when I was working at Download, was very tired and got a chance to lie on some grass behind the stage, they did a good job of putting me to sleep
