by Stewart MasonThe term glitch developed a certain cachet in electronic music circles to describe a specific form of electronic music seemingly inspired by the sound of malfunctioning CD players. It doesn't quite cover the work of the young producer\u002Fremixer Datach'i (Joseph Fraioli), however, because the implications of glitch as a descriptive term suggests a certainly dirtiness, a random quality that makes use of happy accidents. That doesn't describe Datach'i, especially not on his masterful fifth full-length, Shock Diamonds. The key to this album is its sterility: it is as immaculately, pristinely recorded as the average Mariah Carey album, with not a sound out of place. Furthermore, the editing is similarly precise, with not a single beat out of place either. This will to perfection gives Shock Diamonds a certain elegance even at its most rattling. And it gets pretty rattling: beats pile up and tumble over one another, colliding in harsh, unsettling ways that nevertheless have their own logic and grace.
