No. 1 Against the Rush

I can't help but feel that this song is exploring something a bit larger than the dynamics of a particular relationship - I honestly think, and this might be a big stretch, that this song is grappling with "hipster" culture. Admittedly, I don't have a whole lot to base this off of, other than the lyric "This culture's a disease/when you see it through lights." Liars are self-aware; I think that's evidenced by the fact that they've consistently worked to defy easy categorization of their output as a whole. The culture Angus Andrew sings about is likely to be one he knows, and one he's implicated in. A culture that sees itself reflected best in the icy electronica Liars are working with here. A culture essentially based on irony and, therefore, completely unsustainable in the long term. What happens when the hipsters grow up? Will they ever? I think this song plays out as the realization by someone implicated in that culture that there's real fear at the heart of all that nonchalant pseudo-nihilism. "They spiral down, they come back, a dead end, again and again and again and again." The culture's ironic celebration of its own vapidity isn't going to do it for the singer anymore; the vapidity has finally become scary. He wants out, and he wants it out of him. You can hear how it's affected him in those languid vocals - that "fuck-it" spirit is now being turned into a kind of resigned anxiety. He has to "bloody himself awake" to make something of himself; he has to crawl out of the numbing boredom of fake friends and bland hedonism and live in a way that lets him feel good about himself.
No matter what, disillusionment is a big theme in this song. In that spirit, the title No. 1 Against the Rush has got to be meant ironically; it's that self-important self-designation as someone who goes against the grain that the singer is exposing as blind.

False friends who will bring you down. Nothing good can come of such a toxic environment. Seems like the singer is warning another person caught up with this group because he's seen right through them and knows better, perhaps through firsthand experience in once being a part of that group, too.
