There's an urgency to much of Hyper Opal Mantis. Its crunchy basslines seem to search for resolution. "Purple Phase" is one of the album's more elegant tracks, with an emotional melody that gently raises your heart rate. In the same way, a looping synth line in "Saudade," which sounds like a sample from an epic movie soundtrack, gives a sense of something about to start, but never quite beginning. For the most part, though, the album bears its teeth—the flinty acid of "Outremer," the rasping bassline on "Epsilon" and "Soul Surfing"'s drone layers convey a measured aggression.
As an electronic medium adept in emotional and physical manipulation, techno, Letellier suggests, is an "act of resistance" in an increasingly disconnected world. Hyper Opal Mantis also aims to express more immediate emotions. The album's narrative thrust doesn't always strike true—it's unclear how "destructive, fatal attraction" translates on, say, "Saudade"—but Letellier has a surer grasp of the basics at which he excels, techno that's both thoughtful and primal.
