Lol, I love how everyone on this forum complains about how shitty deathcore is, and then listens to the most mainstream and shitty bands of the style. That's like complaining about how black metal is shitty, when you only listen to Cradle of Filth.
What deathcore bands are worth getting into?
The Red Chord - Fused Together in Revolving Doors (while Clients is good, this album just fucking destroys)
Embrace the End - Ley Lines or Counting Hallways to the Left (Ley Lines has Cop In A Cage, which has one of the most retarded breakdowns I've ever heard in my life lol...and I mean that in a good way)
From Here On - Hope for A Bleeding Sky (featuring BTBAM's Tommy Rogers on vocals, pretty good shit if you liked his vocals on their s/t)
Glass Casket - We Are Gathered Here Today (drummer Blake Richardson from BTBAM and guitarist Dusty Waring from BTBAM are in this band)
Into the Moat - The Design (this isn't really deathcore, it's more tech metalcore, but I recommend it anyway)
Ion Dissonance - Solace (also, not completely deathcore, but it's a must-have)
Nights Like These - Sunlight at Secondhand
