Note: this is a review of the 5.1 mix. I know the thread specifies the Atmos mix, but since the 5.1 is an official part of the package, I feel like it should be fair game to review.
I'm actually disappointed by this mix -- it feels quite front-centric/double stereo to me, much more so than I would've anticipated based on the music. To my ears, there's not a ton of unique content in the surrounds (as far as stuff that's not also in the fronts), except for obvious things such as the vocals in the second verse of Radio #1 ("melancholy snipers", etc.) jumping from speaker to speaker. Even there, though, at those moments, those vocals are pretty much the *only* thing going on in the surrounds.
I was hoping for this album to be opened up more, and I don't feel like this mix accomplishes that. A lot of the time, it feels like there are keyboards and other things smashed up front that could've been uniquely moved to the surrounds and helped the album to breathe better.
In a lot of ways, this mix reminds me of the 5.1 mixes for the Bjork albums, which disappointed me for similar reasons.
I voted an 8, but not particularly enthusiastically.
