Palecurse & Ashes Of Ares, both of which I made posts about.
Palecurse is really good emo/post-hardcore with gritty/shouty female vocals that balance angst and melody. I'm enjoying it a lot.
Ashes Of Ares is among the worst music I've ever heard from 'veterans' on a real label. It's bad in every respect, and the only good song on it is the cover (even though it's shit compared to the original).
August will at least have a couple of things to listen to. I think As December Falls could be good, but I don't expect much of anything from Three Days Grace or Rise Against. They're still something to break up the monotony.
Oh, and of course there's the Halestorm album. I won't try to categorize it yet, since I'm under embargo until Monday regarding that.
