Try Speedwolf - Ride With Death it's really good!
There's also a Black-Thrash movement that started recently in Norway, I think. I don't remember any of the bands names though... xD I'll post here if I find out.
Also try Old - Nocturnal Ritual (EP), I've never heard their full lenght, but if it is anything like Nocturnal Ritual it's good for sure and Black Magic - Wizard's Spell, which has a touch of Slayer and a little bit of Iron Maiden.
EDIT: Just found out those Norwegian black-thrash bands: Töxic Death, Condor, Inculter, Deathhammer, Nekromantheon, and there's more I think! Just remembered another one (this one from Greece)! Omega - Second Coming, Second Crucifixion
