Jamie Roberts has been experimenting since his last release as Blawan. In 2016 he debuted two new aliases, offering introverted and deconstructed takes on the textural techno he puts out on his own Ternesc label. Roberts returns home with a refined sensibility, offering a double EP that's subtler than his last Blawan records—even when it bangs. Though the six tracks on Nutrition might seem straightforward, there's a delicacy to even their coarsest sounds. This includes the bullfrog's rasp on "Fawner," with each melodic element bristling and shifting in response to the others, as if they shared a miniature musical ecosystem.
