I personally love Testament's ballads and generally like when bands try to show their other side at a song or two. Songs like that go well with thrash albums and give them a nice pause just to hit you again. Chuck does sound different on Cold Embrace than on the earlier ballads. I really appreciate his performance on the whole album and how he goes new places with his voice and pushes his limits. Too bad he wasn't experimenting that much when he was younger. I think that from a band with such skills one should expect some variety, and Chuck and Testament have done that without losing coherence. If I'm looking for relentless thrash assault with no place to breathe, I'll go with Exumer or Morbid Saint and enjoy it a lot. Testament has, however, always been much more than that in my eyes. They're beyond what an album belonging to a given genre "should" sound like (i.e. in Thrash's case: at least 80% fast songs with samey riffs, shred leads and shouted vocals - as some seem to define it).
As for the whole album - I still haven't had the chance to give it as many spins as I need to have a firm opinion. However, there's no denying it's Testament at their best. I absolutely love A Day in the Death - probably my favourite song for now. I'd love to see them even more melodic and go a little bit more proggy at times (with such musicianship it's natural to break boundaries), and to extend the classic thrash patterns verse-chorus-verse-chorus-bridge-lead-verse-chorus more frequently. Still, this album is a perfect progression for them. Stellar performance by every member, great production too. Some of the shouted choruses may be hard to get into, but there are no weak points here, really. Well, perhaps Rise up is the only song I could live without, 'cause it's so obvious it's been written for the purpose of live performance and is too hokum at places. I didn't like More than meets the eye for the same reason at first.
I agree Last stand for independence is very similar to Henchmen ride, but for me it's a way, way better song in every aspect. Each of the covers is absolutely killer and each of the originals was approached in a different way, which is very cool. Chuck's vocal solo on Dragon Attack is unexpected and wonderful, although too short imo.
Anyway, it's great how they manage to explore new territories, but still remain the Testament sound. This album is much more musical, natural and much less pushed than Formation (which I still love). Where Formation was clearly a comback album, this one is done by a more confident, mature and cohesive band, aware of its strength and vision. Truly, a masterpiece.
