rheom Builds Sound as Temporary Architecture on _729.root

The Bilbao-based Polygon Network returns with an album of signal and subtraction—eight segments of experimental electronics that lead the artist rather than the other way around.

With over 80 releases, Bilbao’s Polygon Network has cultivated a catalog that rarely asks for attention yet consistently refines a language of synthetic restraint. _729.root, the latest from rheom, continues that work—a single piece split into eight segments, built from the ground up through subtraction.

The album operates less as a set of compositions and more as active scaffolding. Pulses and undulations form from minimal signal chains, coalescing into a cohesive architecture where each sound seems reduced to its most necessary state. Micro-shifts in timbre and tempo work against any fixed sense of ground, leaving the music to resolve as it unfurls rather than declare itself from the first bar.

There’s no overt narrative here, no traditional melodic hierarchy. Instead, the album inhabits what could be called a post-IDM condition: a space where machine logic and synthetic interiority ripple outward from lineages running through early Warp’s Artificial Intelligence series, Sakamoto, and the fractal systems of Aphex Twin and Plaid. Here, complexity isn’t a display of virtuosity but an emergent behavior—sound that thinks while it unfolds.

rheom doesn’t pander to accessibility, and the work is all the more alluring for it. It occupies its own logic, unconcerned with external validation. In a climate of constant sonic excess, that restraint registers as a mark of clarity.
