Obstacle 1
Obstacle 1 is Interpol's most perfectly constructed song and still the definitive introduction to the band. Kessler's opening guitar line announces itself as something fully formed — the interlocking, arpeggiated pattern that follows is one of post-punk revival's most recognisable riffs. Dengler's bass is a third guitar line happening simultaneously. Banks delivers one of his most compelling vocals over the top of it. Nothing in the catalogue surpasses the way all four elements lock together here.
Banks' lyrics on Obstacle 1 follow his characteristic approach — imagistic, elliptical, resistant to simple interpretation. The song's emotional impact comes from the space between the words rather than any single line, which is consistent with how the band treated language across the debut.
