Recently hailed as the grime track of the year so far by FACT Magazine, Quartz has been causing quite a stir amongst fans and fellow artists alike. Engineered by Dublin-based producer Bloom, it is a track of real and resonating menace that utilises all of grime's chaotic genius in a silky, strikingly coherent manner. A fairly lengthy introduction builds to a crescendo of searing bass kicks with innovative arcade sounds, sirens and muffled dialogue all used to stunning effect. Such complexities are easy to overlook in the face of sheer impact but Quartz does its best work in proving that grime need not change its spots in order to make a big impression. A case of immaculate fine tuning over complete genre overhaul, it has already won favour with a whole host of big-name selectors and has earned heavy rotation on Rinse FM in particular. Remixes come courtesy of stateside virtuoso Starkey and the excellent Slackk, whose Raw Missions EP was recently released on Local Action to widespread acclaim. Starkey's effort is typically bruising as he fuses the original with trademark 'Street Bass', a title coined to describe his own bass-laden, trap-infused take on grime, to wonderful and powerful effect. Slackk's effort is perhaps more unusual, himself opting for a bold 160 edit of the original that adds genuine depth to the release as a whole.
