I'm a little late to the party here, but Anthrax has been one of my favorite bands since I first heard State of Euphoria in 1990. I love their new album from front to back, especially I'm Alive (I've always liked thick sounding 12/8 songs), Fight 'Em, and The Giant. Charlie's drumming is still top notch (probably one of the most underrated metal drummers of all time) and the sound is "vintage" Anthrax from back when Joey was behind the mic.
I forgot how much I missed Joey's vocals. Bush was nice and brought a different flavor to the group, but Anthrax's aggression left with Joey. With Bush, Anthrax became a thicker version of Armored Saint, IMO. But this album was pure "balls to the wall" and was worth the wait.
