Propagandhi. Supporting Caste comes out on March 10, and it's out-fucking-standing. Already an early candidate for album of the year in my book. It's punk rock, but they have a metal edge to some of their riffs (the intro to "Dear Coach's Corner" is some of the best thrash I've heard in a while, even though it only lasts a few seconds). They also write unbelievable lyrics. Definitely worth checking out.
I also liked the new Cattle Decapitation.
