I wasn't even going to review this initially, and I'm still barely going to do so now. The words "bad Vader album" have no place in the English language, unless they are preceded by "I have never heard a" or some similar phrase. Additionally, the band hasn't really changed their sound in years. Thus, there's not much to talk about that hasn't already been said of their music in general a million times.
On the heels of 2011's colossal triumph, however, fans all have one big question on their minds: is this as good as Welcome to the Morbid Reich? The answer is no, it's not, but it's close.
By now, every death metal fan on the planet knows what Vader sounds like, so I'm not going to rehash that. I would like to point out, though, that Peter continues to have one of my favorite voices in all of extreme metal. As for why this falls slightly short of its predecessor, it's hard to give a specific, concrete reason. This is basically one of those instances of "it's exactly the same, only not quite as good." Of course in this case it still means this was an excellent, well-written, powerfully-performed death metal record with Vader's distinctive personality all over it.
In short: it's good, go buy it. If you like Vader, you'll like this (but you already knew that). If you don't like Vader, then I'm not sure why you're even bothering to read this.
