ZAO was founded at the beginning of the seventies by Yochk'o "Jeff" Seffer (saxophone, clarinet) and Franois "Faton" Cahen (pianos), both ex-members of MAGMA's first era, which includes the albums "Kobaïa" (1970), "1001 centigrades" (1971) and "Uniweria Zekt-the Unnamables" (1972). In this first album from ZAO, "Z = 7L" (1973), the very complex melodic instrumental layers are enriched with the wonderful voice of Mauricia Platon (with its kobaïan accents). ZAOs progressive/zeuhl sound has long been sought after by collectors and finally their first album is available again on LP, in a deluxe gatefold edition on 180 gram vinyl.
