Wire’s last album, 2013’s Change Becomes Us, found them in a rather unusual position – with one foot in the future, and another in the past. Unlike most bands of their age, the latter position was considerably more unusual than the former. It found them dealing with unfinished business, by tackling material that was lost in their first split in 1980. Of course, most of it bore no resemblance whatsoever to those songs (if that’s the right word) that had emerged on 1981’s spectacularly perverse Document & Eyewitness (deservedly reissued last year). Even when Wire are looking back, they can’t help but move forward.
