Before I say anything, I think it's only fair to mention that this is exactly what I expected of another Mogwai remix album. We need only to look at the artists they have selected for the job to see that it's not going to be an easy listen. There's none of the usual canon for this genre on remixing duty, i.e. the four tet and burials of this world, despite that this is exactly what most of their audience want. Therein lies the problem, that there seems to be a fundamental discrepancy between what influences Mogwai and what influences their audience. They make their own form of gritty yet cinematic post-rock, but none-the-less, they are post-rock and as a result, most of their followers ascribe to that aesthetic. On the other hand, Mogwai's personal influences appear to stem from a destructive/punk aesthetic, which is far more apparent on their earlier records - and through their choice of producers/artists for this album.
Therefore, expect a lot of noise and not a lot of melody. There are a couple of saving graces to the record, namely Umberto and RM Hubbert's efforts - and Zombi's remix has a great 80's electro feel that just falls short of the mark when it fails to progress any further. But overall, it's dense, obtuse and seemingly intentionally under-produced - just the way they like it.
