If The Black Dog represents the meditative, introspective aspect of Dust Science's output, then System 23 is the opposite pole. Honing their rhythms by devastating a series of parties across Britain, System 23 represent the ultimate distillation of northern pile-driver techno.

One More Line is anthemic four-four hardcore. It's a single-minded peak-time banger with buckets of attitude. Peaker is a mind-bending circular throb, but it's not mindless: it layers blistering soca-fuelled percussion over stop-start loops. Exit sounds like the end of the world. Volcanic rips of noise resolve into a soundscape tinged, incredibly, with gospel.
