Terrorizer - Darker Days Ahead
It boggles me that so many prefer the debut to these later releases. I honestly consider this one-onwards to be superior!
I usually don't listen to too much Metalcore from this era, but I can find a lot of different metal influences in the compositions from this band. At times they sounds like Fear Factory, must be Dino. If I remember, I was pretty much anti-metalcore and breakdowns and stuck to Thrash revival bands during this era.
^For a long time I just couldn't get into metalcore. Over the years, though, my stance had softened and I actually enjoy a good deal of metalcore bands these days.
