Pulsar is a French progressive rock band whose influences include Pink Floyd and King Crimson, plus classical musicians and composers such as Gustav Mahler.

The following year, the group recruited bassist Michel Masson, who later collaborated with them on The Strands of the Future (1976) and Halloween (1977).

In the early eighties, together with director Bruno Carlucci, in musical theatre, Pulsar adapted a short story by Austrian novelist Peter Handke: "Bienvenue au Conseil D'Administration!"

The quintet comprised Gilbert Gandil on guitar and bass, Victor Bosch at the drums, Jacques Roman on keyboard, and Roland Richard playing the flute and saxophone, along with Louis Paralis taking the place of Michel Masson.
