I still miss Conducting From The Grave, they were so good. But that aside here's some of my favorite MySpace deathcore bands:
From A Second Story Window, Screams Of Erida, Forever Is Forgotten, The Last House On The Left, A Breath Before Surfacing, Make Them Suffer (kinda cutting it close with Neverbloom releasing in 2012), Molotov Solution, She Killed Poetry, Angels Beneath Me, From The Shallows, A Different Breed Of Killer, And Hell Followed With, Burning The Masses, and From Graves Of Valor
There's a lot of newer bands with a very similar style to old MySpace deathcore too so here's some of my favorites for that:
Tracheotomy, Psycho Frame, Tactosa, Mantikore, Thus Spoke Zarathustra, Razel Got Her Wings, papercut, and Balmora
