Barricade, already known as the roots of ZNR, were a radical French commune formed in 1969 by over thirty musicians / non-musicians around François Billard (saxophone, voices, harmonica) and Gérard Lapeyre (violin) in Marseilles. They had wandered from place to place, changed their members one after another, and gigged on various stages in France around 1970.

In 1973, they were split into two Barricades - one is a radically political & anarchic music outfit around François named Barricade Crève-Vite-Charogne (aka Barricade CVC), and another a musically experimental project called Barricade II around Roquet Belles Oreilles (called Hector Zazou later) and Joseph Racaille. The two Barricades had refused any record release throughout their active period in any cases (although Virgin Records had tried to persuade Barricade II to release albums and to go on a tour in England).

Barricade CVC were disbanded in 1973, and also Barricade II in the following year, when almost all of their material might be destroyed. Hector and Joseph formed chamber-rock unit ZNR later.
