Its namesake is fitting, because when it comes to instrumental post-rock, we’re over it – mostly. We get it – it’s traditional rock instrumentation with non-traditional song structures. Mogwai. Sigur Ros. Explosions in the Sky. Still, when it works, it works, and Toronto’s Old World Vulture are on to something. Brevity – at least in post-rock terms – is its modus operandi; with most songs clocking in under five minutes, their songwriting is refreshingly free of superfluous dramatic tension and clunky soft-loud dynamics. There’s no carbo-loading here. Instead, these noisemakers blend prominent, dream-like synth – perhaps their calling card – with droning guitars, thunder-crashing cymbals and a dash of electronic glitchery for good measure. It doesn’t have the sonic heft of metal-leaning acts such as Pelican or Isis, but true to its moniker, the foursome’s finest moments are their grungiest, scrappiest and loudest – best exemplified on tracks such as “Changing Thoughts” and “Bastard Engine.” And that’s saying nothing of “How the West Was Lost,” a screamer of a cut boasting a guitar tone so filthy it makes you want to exfoliate. The downside? At six tracks, there’s barely time to construct a cohesive sound. But as a debut EP, there’s plenty of promise here.
