The Agonist, a band from Canada, just released their album Lullabies for the Dormant Mind and it is absolutly amazing. I thought their first album would be impossible to beat and after I listened to one song from the 2nd album, I was convined that it was way better than the first. They play metal and they have a female vocalist who doesn't do pussy vocals.

Listen to The Tempest, it's the best song I've listen too so far.
