Lamb of God are a good band, they write great lyrics and have some excellent riffs. I don't like their new album as much as I liked Ashes of the Wake, but it has its moments. "Redneck" is an awesome song, I like the way it contrasts a simple structure with highly technical riffing.

Damaged, I can see why you don't like the vocals in extreme metal! Personally I find there are some "screamers" who I can listen to and enjoy, and others (like Anders Friden from In Flames) who are just grating.
