Georgia metalcore band swims waters crowded with such noisemakers. But they rise above with convincing musical brutality and lyrics that beg a listen. They're screamo and noisy to be sure, but melodic overlays creep in and out, while the occasional epic track slowly builds, exposes its fangs and then blasts out the amps like a pissed pit bull. There's plenty more where that came from, as tonight's bill features nine other like-minded bands. $15-$18. Amos' Southend. www.amossouthend.com.
