As the `80s rolled into the `90s, metalcore, a new breed of metal-tinged hardcore, crawled out of suburban garages and urban bedrooms, nursed by the straight edge and emo scenes. Cleveland, Ohio's Integrity pounded a thick metal stake into the heart of the straight edge punk scene. More recently, Earth Crisis has inspired a new legion of young wanna-be guitar heroes who borrow from the groundbreaking work of Slayer and Metallica. More than just the sound, these bands also brought the politics of the scenes from which they were born. The straight edge bands have become more sharply political and radical, while other bands use inner angst as their rebellious message.
