This is definitely the best of the Bostaph-era Slayer records. It doesn't stand up with their best, but given everything they've been through I think it's perfectly fine as a statement informing us that Slayer aren't dead. The next one, I'm sure, will be even better.
The Blu-Ray is well worth the upgrade too. Full concert from Wacken 2014 plus a cool making-of documentary.
I liked Starbound Beast well enough, but I wouldn't consider myself a Huntress fan. This record didn't really change my mind either way. They're fine, but they don't do enough to stand out in my opinion.
I have no knowledge of Bring Me the Horizon's early days. I first heard of them when Sempiternal came out and fans seemed to be in open revolt. I liked that record well enough, particularly some of the lyrics, but this one is a fair bit better. Sempiternal was clearly a transition, and this one has the advantage of the band going deeper and doubling down on the sound. Reminds me of the Deftones a bit, which is a plus in my book.
The album's pretty good. The one dog is Destination: Nowhere, featuring Matt Heafy from Trivium on vocals. I love Matt's voice, but somebody screwed him in the mixing process because his vocals are really, really low in the mix and they sound as if he put almost no power behind them. Shame. Other than that, musically this album does just fine.
The DVD's not really worth the money though, I must say. There's hardly anything featuring the singers, it's mostly just Mike Portnoy filming himself drumming and Dave Ellefson telling us that every track is a good song. The quality of the footage is really low too. That was a disappointment. I'd say buy this, but go for the regular edition.
