So I love metal and everyone in this thread, aside from As I lay Dying and All That Remains, posted classic metal. I'm more into the newer age stuff but August Burns Red tends to be well received with most metal fans:

Finally my dudes Wolves at the Gate from Springfield, Ohio...they are really blowing up and they aren't strictly metal, but they can destroy on the occasion:
