After collaborations with Sandwell District type Silent Servant, Santiago Salazar teams up with fellow LA resident Roque Hernandez for the latest slice of modern techno classicism on the Historia y Violencia label he fronts. The A Side sees Droid Behaviour duo Raiz turn Hernandez's "Izalco" inside out, bringing forth a wall shaking skeletal throb which quickly settles into a undulating locked groove of relentless pressure and dancefloor menace. Salazar takes the B Side with the less ominous, more retrospective aerodynamics of "Retiro", with only the industrial hiss of percussion to distract from the ever growing procession of ethereal melodic bubbles. Two variations on a timeless theme that come in a lovely embossed sleeve!
