First impressions:
Warbringer - War Without End: Sounds like Bullet for my Valentine.
HAHA, just kidding. This is the shit. Thrash Metal has to be one thing: fast. And this IS fast. Fast, brutal and heavy as hell.
Evile - Enter the Grave: Sounds like Trivium. HAHA, not really, but the singing is a little bit like on the Crusade. Really old school. Not so much pushing like the warbringer, but still very good (it's like comparing Slayers Reign in Blood with Kreators Pleasure to Kill).
And I think both are even a little bit better than the last Slayer, Sodom, Exodus and Destruction. Not much boring midtempo. They both go forward with power and velocity.
