~new thrash metal/speed metal/ one of my favorites: trivium
~Deathcore/black: carnifex, suicide silence, born of osirus
~"pure american metal": lamb of god
~blast beat/break beat metal/hardcore: slipknot (albums: the subliminal verses and earlier, theyre new stuff is more towards heavy metal but still just as good! its called All Hope is Gone)
~I support children of bodom as well (good choice syndrome.)
so thats good for starters. I love metal!! its a lifestyle, not just a genre!
