Quartz

When the Metalheadz logo flashes on the screen, we know we’re about to get a lesson in sonic architecture, and Quartz at the Keep Hush Live Bristol takeover does not disappoint. This is pure, unadulterated jungle and drum & bass for the purists and the new converts alike, all heads nodding in unison to complex breakbeats. The vibe is focused and intense, the kind of session where the only light comes from the strobe and the glint off a well-polished Technics. Technically, it’s a powerhouse display, averaging a fierce 168.7 BPM and frequently using the bright, energetic key of 12A as a launching pad.

The energy balance is evenly split between a powerful low-end (0.49 avg) and a detailed, rolling mid-range (0.44 avg), crafting a sound that is both devastatingly heavy and intricately detailed. The mixing is taut and relentless, a seamless flow of originals that showcases Quartz’s signature sound. The crate here is, unsurprisingly, stacked with his own productions: the menacing opener ‘Sycophants’, the brain-melting modulation of ‘Ganzfeld’, the absolutely crushing weight of ‘Skeng’, and the atmospheric depth of ‘Falling Gradients’. Each track is a statement piece from the Metalheadz catalogue, demonstrating a mastery of tension, release, and rhythmic innovation.

The journey is a linear assault: it kicks off with the foreboding ‘Sycophants’, peaks with the relentless, twenty-minute epic ‘Skeng’, and concludes with the collaborative fire of Halogenix & Strategy’s ‘PFTD’. A Quartz live set that is essentially a greatest hits of modern drum & bass.
