The French equivalent of prog-rock bands Yes and Genesis, Atoll recorded four albums in the mid- to late '70s with a lineup that stabilized by the time of the group's second album. L'Araignee Mal (1975) included vocalist/percussionist André Balzer, guitarist Christian Beya, bassist Jean-Luc Thillot, keyboard player Michel Taillet, and drummer Alain Gozzo. Gradually commercializing its sound beginning with third album Tertio, Atoll released only one more studio album (plus a compilation) before breaking up. In the late '80s, however, a new, pop-oriented version appeared. Including only Beya from the previous lineup, the band released L'Ocean and the live album Tokyo C'est Fini (both 1989).
