Orphx have been creating their unique fusion of rhythm and noise since the early 1990s, combining and recombining elements of techno with the experimental techniques and critical spirit of industrial music.

The project began in 1993 as the trio of Rich Oddie, Christina Sealey, and Aron West, creating improvised recordings and audio/visual performances inspired by industrial, power electronics, and other forms of extreme music. Their distinctive sound used powerful layered rhythms, modulating soundscapes, and processed vocals and samples to explore themes of psychological conflict and social control. By the mid 90s, Orphx was drawing further inspiration from the more experimental fringes of techno and electro and working closely with Germany's Hands Productions label. Studio recordings were primarily created by Rich Oddie, while Oddie and Sealey continued to develop new live performances together. During the late 90s and early 00s, the duo gained an international following as one of the pioneering acts within the European "rhythmic noise" scene. Oddie and Sealey have collaborated on both live performances and studio recordings over the last decade, further developing their fusion of techno and industrial music across a series of acclaimed releases on the Sonic Groove label and remix work for a wide variety of artists, including Front Line Assembly, Conrad Schnitzler, Nomeansno, Oscar Mulero, Perc, and Svreca.

Orphx have refined their sound across numerous releases and many changes in tools and techniques, moving from reel to reel tape machines and scavenged instruments to software sequencing and processing, and then back again to hardware following Sealey's adoption of modular synthesizers in the late 00s. Oddie and Sealey are renowned for delivering improvised live performances that combine modular synth, drum machines, software, and live vocals. They have toured throughout Europe, North America, Japan and China, appearing at international festivals such as Berlin Atonal, Katharsis, Mutek, Unsound, Rural, and Labyrinth, and regularly performing at techno temples such as Berghain, Tresor, and Khidi. In recent years, they have been working on new audio/visual performances using ultrasound and multi-channel speakers systems, working in collaboration with video artist Patrick Trudeau and McMaster University's Institute for Music and the Mind. Other active collaborations and side projects include Orphx + JK Flesh, Eschaton (Orphx + Ancient Methods), Ontario Hospital (Rich Oddie + Huren), and Oureboros (Rich Oddie + Aron West).
