If the moshers that adorn the cover of their latest EP don't give it away, first song Raison D'etre will: Shitripper like things fast, loud and heavy.
The Auckland-based punk act only know one way forward - full throttle, and that's exactly what they deliver on this blistering nine-track EP, which clocks in at a barely believable 10 minutes.
That's thanks to short-and-sweet hardcore guitar assaults like We Will Be the Death of You and Rat Fight, led by the dual boy-girl vocals of the six-piece band's singers.
Their old-school attitude and lack of mainstream suitability might not appeal to everyone, but songs like For Ages 12+ sure sound exhilarating in a heckle-raising, fist-pumping kind of way, and achieve the band's ambition of honouring their underground heroes Circle Jerks and Minor Threat.
It's a shame Shitripper don't explore some of the ideas here more thoroughly, like the riff that runs through the mere 17 seconds of Head First, or the quickfire rants and slow-motion chug of Plastic Shit (which comes complete with a scathing environmental message).
