Killswitch Engage has always incorporated melodic death into their music, but on their latest release, the melodic death really dominates. here and there there are metalcore breakdowns. they still rock though. I disagree with the one who says metalcore is about ex-girlfriends. I own several metalcore CD’s and not one of them mentions relationships gone bad. somebody better reread the lyrics on all their CD’s. other metalcore bands to consider are Himsa, Zao, Demon Hunter, Still Remains, the Showdown, A Life Once Lost, Underoath, As I Lay Dying, Underoath, Watch Them Die, Hedfirst, Cataract, and Winter Solstice.
