Glass Wall Scenery, the first full length of canadian metalcore outfit A Dead Motion, is a good exemple of the genre done right.
Okay, I admit that they sound a bit too much like August Burns Red, but there's nothing wrong with that. The technical yet melodic riffs will keep you interested and the heavy breakdowns will take you to headbanging heaven. Only downsides are the laughable at best clean singing ( See The Devil Wears Prada ) and the ridiculous lyrics. Don't judge too fast and give it a listen if you're into fun metal music.
