Musically - the album is great. Leprous has its own style, so if you like this band, you will definitely like it.
The 5.1 mix is very good. There is a bit going on in the back - additional guitars, synthesizers, sometimes backing vocals.
In Dolby Atmos I only listened to the first three tracks and unfortunately it is another Atmos mix of Bruce Soord, which I do not like. Too many main elements can be heard constantly from the overhead speakers, which is tiring for me - I mean the main vocals and a large part of the guitars. For me it is very unnatural. I know, Bruce has this style of Dolby Atmos mixing (I have albums by Katatonia, Jethro Tull, Yes, The Pineapple Thief, Tesseract), but I simply do not like it. When it comes to Atmos mixes - I definitely put Steven Wilson in the first place.
However, I emphasize that I love Bruce Soord's 5.1 mixes.
And this Leprous album - I recommend it!
EDIT:
I listened to the entire album in Atmos today and I actually like it. I'll still say that the lead vocals should be moved forward and lower from the top. I also think that there's a lot more going on in the back in the 5.1 mix.
I'd rate it like this:
5.1 mix - solid 8,
Atmos mix - 6.
And musically I like the album more and more.
