Style-wise, Shapes isn't marking a great departure from Gomez's jams. Rather, it highlights certain aspects the group includes in their music. Plus, the album allows Ottewell space to breathe. And he has never had as much oxygen as he does on Shapes.
It's rather far from being a poor album, but there's no real argument to be made for the existence of as a standalone work. For that, a bit more tangential newness should be expected, but Ben Ottewell is disinclined to provide it.
