(There is a point where the track almost threatens to unravel; instead, it shifts frame - changes gear - and becomes something else: it's a ploy worthy of Reich or Phil Glass; a musical Glass Bead Game...)
"Horse Cortex" is Apollo 440 boiled down to a single reductive libidinous geetar lick - deceptively gestural; a nod to The Boogie, The Riff - that slowly backpeddles against the flow and (de)volves into a foreshortened self-quoting version of itself. It jogs on the spot, shadowboxes its own echo, then fuses with a ratcheting rhythm that sounds like a 19th century steam-locomotive or a cotton-mill: it becomes a pumping Ur-UnGuitar that unstrings itself and morphs into strobing soundsystem swirl. Dry-ice speaker exhaust; Status Quo heard from behind a quivering speaker-stack, a riff carried by an ill-wind from 1991. Endlessboogieunfurl.
And this is what Neil is great at doing: creating structures that stretch themselves out to near breaking-point, that threaten to collapse - to widen into an unsustainable, unlistenable gulf - but turn out to be far more resilient and malleable than the listener ever suspected; he builds riddims and soundquotes that transmigrate out into endless, ever-widening vistas, hinting at the infinitely-elastic under-nature of the physical world that we inhabit and take for granted on a daily basis.
There are, errrm... five other tracks on this album and they're all pretty great.
