The obvious thing that Andy Falkous is very good at is making his making his voice hit the speakers with a blunt, violent force. This is especially powerful when paired with a sharp, stabbing riff, like the one found in the first half of this song. The less obvious thing that Falkous does well – and really, that's kind of an understatement, he truly excels at this – is in constructing songs that cycle through a series of hooks before moving on to other ever-escalating melodic patterns. It's an unusually sophisticated strength for a guy who essentially makes heavy, venomous punk rock.
"Polymers Are Forever" is split down the middle – the first half is more bludgeoning, his voice alternating between nasal hectoring and throaty shouts. The second half seems to expand in scale, with a quasi-anthemic chorus that seems to stretch out from close-up to widescreen panorama. (Structurally and tonally, it's rather similar to Wire's classic
"Map Ref. 41°N 93°W.") In this section, Falkous' voice is more distant and pitiless, like an indifferent god. With this contrast, the implied violence of the first part seems almost warm and intimate - undeniably human. The rest of it, though – it's all science.
