Heldon was a French electronic rock band originally active between 1974 and 1978, and led by guitarist Richard Pinhas.^[4] Other members included synthesizer player Patrick Gauthier and drummer François Auger.^[5] The name of the band was taken from the 1972 novel The Iron Dream by Norman Spinrad.^[6]

Influenced by the work of Robert Fripp (and sometimes evoking his work with Brian Eno), the music of Heldon blended electronic and rock forms.^[4] The first releases under the name Schizo, and later Heldon, were self-produced and self-distributed.^[7] Jim Dorsch from AllMusic would later describe Heldon's seven albums as "groundbreaking."^[4]

Pinhas had previously led the band Schizo and also released six albums under his own name.^[7] Pinhas has worked with numerous collaborators, including musicians of the band Magma, and music journalist and multi-instrumentalist Hervé Picart.^[8] He was also associated with philosophers such as Gilles Deleuze (of whom he was a student).^[9] and Jean-François Lyotard,^[2] as well as writers such as Norman Spinrad and the essayist and novelist Maurice Dantec.^[7] Pinhas completed his PhD in Philosophy from the Paris-Sorbonne University in 1974, teaching for one year and beginning Heldon.^[2]

The Pinhas/Heldon catalog was reissued on CD by the label Cuneiform, and later Bureau B.^[4]
