Vertigo Index. What they play in Hadak Ura is still grind related (especially some drumming parts) but there's also a lot of hardcore elements (vocals, mid tempo groove), hardcore of a raw and very dark kind. their first release (digital only for the moment) called Forever dying // Forever dead sounds really intense and coming from the guts, something more violent and "real" than most of those "blackened hardcore" bands that appeared these years. Grind school is the best school!
My only complain would be that the samples / dark ambient parts last a bit too long maybe (no big deal). Otherwise it's really good.
