As the co-founder of the label All Centre, DJ Pitch created a home for some of the crunchiest leftfield club tracks around. The London-based artist’s own productions are more unpredictable, touching on everything from crinkly techno to vocal-driven avant-pop. Released on his new imprint Blunting, DJ Pitch’s latest two-tracker, Juan Mecanico/Luis Contadora, is at once lurching and sugary. The A-side, “Juan Mecanico,” rides a dembow groove peppered with glitchy vocal samples and frosted synth pads. The back half, “Luis Contadora,” is comparably tense; across four minutes, taut bleeps flicker beneath clicky drums. Juan Mecanico/Luis Contadora is a rubbery addition to a catalog that seems to be in a constant state of evolution.
