There's a local band that are very good called Monolith, who I guess are largely influenced by deathcore. I'd suggest checking them out if you're generally a fan of heavy music.
It pains me a little that emo has become a general, all-encompassing insult rather than a descriptive term for a certain sound. I'm fed up being recommended a band that's 'post-indie mixed with the style of Revolution Summer-era D.C. bands'.
I know people who are into deathcore that are big fans of Martyr Defiled. Maybe they're worth checking out?
