Karl O'Connor, professionally known as Regis, is a seminal figure in the evolution of British electronic music. Emerging from Birmingham, England in the early 1990s, Regis was instrumental in pioneering the stark, industrial sound associated with the city's techno scene. As a co-founder of the influential Downwards Records alongside Peter Sutton (aka Female), his work catalyzed a new wave of abrasive, dark, and rhythmically innovative techno.

Regis' productions are marked by minimalist structures, relentless percussion, and an uncompromising approach to sound design. Throughout his career, Regis has produced under various aliases and collaborated on acclaimed projects such as British Murder Boys (with Surgeon) and Sandwell District. His solo and collaborative releases have consistently pushed the boundaries of techno, blending elements of industrial, EBM, and post-punk influences.

O'Connor's DJ sets are celebrated for their intensity, skillful narrative, and deep understanding of dancefloor dynamics. Regis’ enduring impact extends beyond production and performance; he has played a significant role in shaping the ethos and aesthetic of underground techno. His discography, featuring standout albums like "Gymnastics" and numerous seminal singles, continues to inspire generations of electronic musicians.

Despite his elusive public persona, Regis remains a key tastemaker, revered for his artistry, innovation, and unwavering dedication to the underground spirit of techno.
