Unter Null is the solo project of Erica Dunham, an electropunk/industrial music artist from the United States, who began her venture into the dark electronic music scene in the early 2000s. Rooted in the aggressive blend of industrial and EBM (Electronic Body Music), Unter Null quickly established itself with a distinctive fusion of harsh electronic beats, scathing vocals, and melancholic melodies. Dunham, through her Unter Null persona, is known for exploring themes of personal struggle, emotional conflict, and societal criticism, all while wrapped in a cocoon of pounding rhythms and abrasive synth lines.

Unter Null’s body of work is characterized by its intense energy and personal intensity, with releases like "The Failure Epiphany" and "Sick Fuck" exemplifying the project's dark and confrontational style. The project has evolved over time, with releases such as "Moving On" and "Mixing On" revealing a more reflective and textured sonic landscape, indicating Dunham's willingness to expand her musical horizons. Despite the variations in sound and experimentation with different subgenres within the industrial realm, Unter Null’s music remains a cathartic outlet for both the artist and her listeners, resonating with fans who crave the darker side of the electronic music spectrum.
