Earth Rocker by Clutch wins this year for me so far.
The newest Soilwork album, The Living Infinite, is quite good. It's too long, but the good songs are some of the best I can remember since Natural Born Chaos.
Looking forward to the new Satriani album. He released the first song, "A Door into Summer", and it sounds...like Satch. Kind of like Summer Song. It's wonderful to know that no matter how much music slowly evolves into a hybrid of commuter beeps and auto-tune, Satch will always be waiting in a corner with an analog recording that sounds just the way you'd expect it to. He's the virtuoso, mostly lyric-less AC/DC and I'm content with that.
