Initially, a studio session was intended with Jimi Hendrix, who cancelled, being ill. Ferré recorded with John McLaughlin and Billy Cobham, guitarist and drummer of Mahavishnu Orchestra, and Miroslav Vitous, bassist of Weather Report.

(the self-same track, Les Passantes, Psaume 151, Le Crachat), that critics would praise as a truly renewal of his inspiration, without noticing these texts had been mostly written in the early 50s.
It was dismissed from the original LP by his record label and was released on 45s one year later (it is included in the album since CD editions).
