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 La Peste, Neurocore, Subskan and Xanopticon.

Luca Maini of Igloo Magazine summarized the album's sound as "Somatic Responses mangled and speeded up to create a teeth-grinding industrial monster, ultra processed and with thousands of razor sharp beats packed together.

[12] For most of Erratic's output, Robbe eschews computer-generated beats and rhythms in favour of "exotic instruments" and contact microphone-derived sounds, which are subsequently manipulated using various audio editors.

The album is unique among other releases on the Enough imprint for its extensive use of microtonality and unresolved atmospherics,[17] described by one journalist as "a spacious, complex, and arguably psychoactive menagerie of integrated electronic soundscapes.

.... a purely abstruse composition of sonic nomogenetics, synthetic coils and unfurling digital helices, producing from the ether intangible imagery of high technology newly conjoined with anthropomorphic sentience".

Duncan Avoid was also performing throughout Europe at this time, including two shows at the Cabaret Voltaire with Shitmat and Chevron, the 2003 Fuckparade in Berlin, and the 2004 Polymorphik Festival in Liège, Belgium.

Many have found the album's fusing and traversing of disparate styles difficult to categorize,[20][21] with one reviewer calling it "so innovative it sounds almost entirely novel, almost totally devoid of obvious influences, to the point of being a new form without a ready frame of reference.

"[22] Similar sentiments were expressed by others, with descriptions ranging from "punchy breakcore freneticism coiled tightly around endlessly twisted ambience and hectic experimental sound sculpture",[23] to "a gaseous contrail of solar noise and ice particles where ambient breaths of watery melodies get heat-flashed into steam, and software-driven drum programming is savaged by extended processor cycles.
