Tucson, Arizona resident Dave Wright whips up his own electronic dust devils on the idiosyncratic SANGRE AZUL. Wright's debut for the late and lamented San Francisco label Visible, TIME MUSIC FOR QUAZARS, mined the 'artificial intelligence' vein of ambient techno; SANGRE AZUL is an autopsy performed on machines, Wright getting down and dirty with his equipment. He's nursing many genre boundaries, and thankfully, all emerge winners by his own hand. "Rocket" blasts off on some gritty analog thrusters, "Xanax" is all filigree and shadow, nuanced synthesizers exalting shifting atmospherics. "Electromagnetic Disembowler," despite the proto-industrial titling, is more an exercise in squelch, bleep and circuit-breaker, low-end synth throbs mimicking a beatbox anthem. No doubt Wright coins these cool, faux-dance electronic ditties in phantasmagorical imagery (the sleek rhythmic contours of "Projectile," the barren, electron-blasted landscape of "Mindsweeper"), perhaps designed to disorient the listener. But his complex sound designs and rugged rhythms don't shake off the salient fact that SANGRE AZUL is one of the more arresting pieces of electronica to have been birthed in 1997.
