When I say Orchid are accessible I mean that fans of things like metalcore and hardcore often also like them, if you're completely out of the scene and all you won't find it accessible at all. That said, a cover isn't the best example of them, something like
this would be. But emoviolence isn't a defined genre, it's really just an umbrella term for any type of hardcore that's screamy and includes lots of (real) emo influence. Something like
this could be included, and that's certainly more accessible than Orchid.
The main problem is the death-metal-esque vocals, of course.
LOL. Saying that would probably piss off actual metalheads far more than me. The only screaming in death metal vocals is backing vocals, anything with screaming lead vocals is almost certainly not real metal (metalcore doesn't count) in fact.
