Heratius

Obscure 1970's French underground band from Montpellier, originally centered around Robert Diaz and Florence Leroy, with other members Armand Miralles and Kristof Temple joining from the band Eos. They debuted with a cassette release circa 1974(?) but are best-known for the privately issued LP "Gwendolyne" published in 1978. A second (previously unpublished) album "Les Boniments" documents recordings from 1979. Heratius could be described as being like a mix of Etron Fou Leloublan and Faust (in acoustic mode that is), with hints of Albert Marcoeur and Red Noise, with music that is full of invention and typically French eccentric touches.
The Heratius album "Gwendolyne" was also much touted by Chris Cutler (of Henry Cow fame) at the time as the French Faust.
