The Document One boys have established themselves as certified production dons. They weave strands from soul, jazz, hip-hop, techno and funk together into something that's always just a bit unpredictable. Well, that's not quite true. The one thing you can predict with certainty is that, every time, they'll do some serious damage in the dance. How Low Can You Get? opens in a sci-fi landscape populated by sweeps of pad and distant shimmers of reverberating hits. As high-pressure swells of bass signal the approach of the drop, digital glitches in the high-end take us further into tech paranoia. How low can you get? Pretty damn low, as the stripped-back, kick-heavy beat supports the drop of weighty sub-shattering basslines. This is dark, insistent and powerful. Girl, on the other hand, might just be Document One's deepest excursion into soul territory so far. An RnB vocal riff, surrounded by loose percussion and fragile keys that meld into pads, hints at where this track is headed. Make no mistake, though, along with the melodic elegance and that beautiful lighters-up breakdown, there's an undercurrent of energy. Expertly constructed surges of bass drive the track onwards under popping beats. This is fluid drum 'n' bass music for raves and airwaves alike. The two tracks on this release are almost opposite in tone, night and day, tech and soul, but the fingerprints of Doc One are unmistakeable on both. It seems there's still a lot more genre-bending innovation left to come.
