"I like the street — the smells, the scents of another world," go the first words of this debut, arguably the most accomplished single-artist dubstep album, and it's appropriate that this producer came out of another world than club culture: Greg Sanders, a.k.a. Distance, was a metalhead before making electronic music, and his banks of synths on tracks like "Confined" have the density of sludgy guitars. Often echo can be a crutch to hide mistakes or make up for little content, but "Night Vision" and "Tuning" in particular show that Distance uses it with near-surgical expertise.
