Jan Robbe (born 14 June 1980 in Ghent, Belgium), otherwise known by his music project aliases Atomhead, Erratic, and UndaCova, is an electronic music artist. He founded the experimental netlabel Entity in 2003 with friend Nico de Gols (aka Kaebin Yield). Jan Robbe is known for expressing various musical styles under different pseudonyms. Atomhead and UndaCova, his two most prominent projects, focus on fractured industrial beats and densely textured DSP sound design techniques, whereas Erratic is a vehicle for pursuing more minimal long-form ambiental directions. Robbe has released music on distinguished labels such as Dyslexic Response and Hangars Liquides, and collaborated with artists who operate in similar aesthetic domains, including Neurocore, Subskan and Xanopticon.
