Her new album is almost entirely about the breakup.
More on the album- It's weird because I don't think any of the songs are actually bad but it feels like she's retreading old ground at times and it isn't as memorable as it should be (I explained briefly how it was different to her previous works earlier). Even though her last two albums were not as well-recieved as this one, they were still rather different/odd. The Haxan Cloak mixed every track on the album but I think if he had a greater hand in the production, the album would have been more sonically interesting. His Excavation album was freaky and dark. His soundscapes, Bjork's vocals/vision/strings and Arca's odd weird bits. It would move her further away from pop though.
There's stuff happening all over this album but there's still a sparseness to it that I don't entirely dig. Still, not a bad album. Quicksand is still the best track.
