The rhythmic content plays off clashing triplet and eighth note patterns that will be somewhat familiar to dubstep fans, but amid their alien landscapes, even the familiar is made strange.

It's interesting, and yet it's in these moments that Driftmachine's hubris becomes evident; for all their laudable abstract experimentalism, they sometimes lose a degree of human connectivity. This music is not quite danceable enough to move a floor, and yet it's too involved to make a great ambient listening experience either. Ultimately, Colliding Contours, though fascinating, is on the cusp of being too mechanical to drift, and too drifting to generate energy. (Umor Rex)
