"Composer, guitarist and electronics innovator Richard Pinhas is recognized as one of France's major experimental musicians. A pivotal figure in the international development of electronic rock music, Pinhas' stature in France is analogous to Tangerine Dream's in Germany: the father figure of an entire musical movement. The pioneering, aggressive music produced by his band Heldon during the 1970s, fusing electronics, guitar and rock, heralded the industrial and techno to come and remains today vital and unsurpassed. The 'Father' of electronic music in France is also recognized as a world-class guitarist whose "diabolical guitar work" (Progression) earns comparisons with Robert Fripp.

Pinhas received a degree in guitar at 17, and a PhD in philosophy from the Sorbonne, studying under philosopher Gilles Deleuze and writing on time and science fiction. He taught philosophy before abandoning an academic career for Heldon, his 3rd band, whose name derived from Normal Spinrad's writing. Over the course of his subsequent musical career, Pinhas' ongoing philosophical studies and interest in science fiction have fired, infused, and continually renewed his music."
