I'm really drunk so I'm doing another post.
Okay, so a lot of people lump slam and deathcore together because they don't listen to either and the idea of "death metal + lots of groove" transfers perfectly between those two. Well, it doesn't. Hate to burst your bubble, but the crossover between those scenes is basically nil. I know there's a lot of people who listen to faggot stuff like The Chasm who enjoy imagining that all the people who listen to Devourment are also eagerly eating up Suicide Silence, but even though I'm that sort of person, it's a very rare character who does such a thing.
Ingested, however, are one of the only bands who actually manages to bring the two styles together in an essentially perfect fashion. Waking the Cadaver was the first band to attempt such a mixture, featuring pure metalcore breakdowns alongside slams, but it seems that Ingested have entered a sort of Whitechapel-style acceptability to metal fans that WtC have not, so they're really the harbingers of this deathcore-cum-slam style. Both slams and hardcore breakdowns are featured, but that's not what really makes them so awesome.
It might seem like kind of a tertiary issue, but for Siege of Amida to actually fund a video for a song called "Skinned and Fucked" and release an album which features nude women getting tentacle-raped to death is a surprisingly big step. It shows them embracing a whole side of extreme music that they basically shied away from for a long time. But beyond that, it makes sense, because Ingested are fucking awesome. They somehow know the perfect way to marry the obsessively catchy elements of both slam and deathcore into a whole that makes you want to listen to tracks like the above over and over again (as I am right now.) This is the future of mainstream extreme music, I think- bands that are willing to embrace catchy metalcore elements alongside some basically undeniable brutality in order to create something so sick and awesome that no one can resist it.
Keep in mind that emo kids in my high school listened to Waking the Cadaver all the time. You're not so special; just add some breakdowns to your shitty Hell's Headbangers retro-death and they'll love it too.
