This right here is a really great iteration of post-punk from the great country of New Zealand and the really great record label Flying Nun. Angular, but not spastic, and really heavy. Super noisy in a really thick, aggressive way, not just washed out all gaze-style. Song structures are drawn out so that each motif can be properly damaged through improvised noise and dissonance.
Unlike pre-60's jazz in which dissonance is used in passing to lead into other chords, these riffs are diatonic and then dive into tritones and weird extended chords created by the ringing out of open strings. Groups like Husker Du used the open strings of the guitar to create nice little 9th and 13th chords, but here they are used in a much more mind-fucking, abrasive manner.
The triumph of this record is Coalminer's Song. You kind of feel that opening riff in your teeth. Just giving your teeth that good ol' in-out. Fuck I'm so pumped and I'm not even listening to it.
For fans of Sonic Youth, Joy Division, and jumping into an abandoned mine on Mars.
