had been initiated on Les Chants Magnétiques and continued on Music for Supermarkets, the album was based around multiple fragments of human voices pronouncing words and speeches in different languages from all over the world, recorded digitally by Jarre and then played back and edited on the Fairlight CMI. In 1985, Jarre was invited by the musical director of the Houston Grand Opera to perform a concert celebrating Texas's 150th anniversary on 5 April 1986. Although he was busy with other projects and was at first unimpressed by the proposal, on a later visit to the city, he was immediately impressed by the visual grandeur of the city's skyline and agreed to perform. Also, 1985 marked the 25th anniversary of the foundation of the Lyndon B. Johnson Space Center; and NASA asked Jarre to integrate the anniversary into the concert. Jarre worked with several Houston-based astronauts, including Bruce McCandless II and Ronald McNair, an accomplished musician who was to have played the saxophone on "Rendez-Vous VI", recorded in the weightless environment of space.

McNair's saxophone piece was recorded by French saxophonist Pierre Gossez and retitled "Ron's Piece". At Jarre's giant concerts in Houston and Lyon, the part was performed by McNair's friend, American saxophonist Kirk Whalum: About 2,000 projectors shone images onto buildings and giant screens up to high, transforming the city's skyscrapers into spectacular backdrops for an elaborate display of fireworks and lasers. Rendez-vous Houston entered the Guinness Book of Records for its audience of over 1.5 million, beating his earlier record, set in 1979. The display was so impressive that a nearby freeway was blocked by passing vehicles, forcing the authorities to close it for the duration of the concert. Several months later he performed to an audience of about a million at his home city of Lyon, in celebration of a visit by Pope John Paul II. Watching from Lyon Cathedral, the Pope began the concert with a good-night blessing, a recording of which appears on Cities in Concert – Houston/Lyon. In 1988, Jarre released his ninth studio album Revolutions, and in same year, a concert called Destination Docklands was planned for September, to be
