While attending Mills she began developing her debut album Movement. Movement was released in November 2012 through RVNG Intl, a record label based in Brooklyn. For the album she used the visual programming language Max/MSP to create custom instruments and vocal processes. Movement received a score of 8.1 on Pitchfork, who stated that Herndon "uses her crystalline voice as a chief input for her laptop, ultimately arriving at a poignant nexus of electronic accessibility and experimentation that owes as much to her academic forebears as her club contemporaries. It's a record with the rare capacity to turn cynics who might scoff at the idea of laptops-as-intimate-instruments into believers." According to The Quietus, "Movement's sound certainly has its forebears and contemporaries – it's possible to detect traces of everyone from Coil and Aphex Twin to Ellen Allien and Laurel Halo in the mix – but equally it contains elements, both sonic and thematic, that are quite unlike any other electronic music currently out there." Also, "Herndon's music reflects the ambiguous nature of our interactions with these technologies. It's by turns sensual, blissful and disturbing, and often hints towards all three states at once."
