Jarre had developed his sound, employing more dynamic and rhythmic elements, particularly a greater use of sequencing on basslines which was mostly achieved using custom equipment.
The release followed by a concert in Paris in 1979. This concert attracted 1 million people, which was Jarre's first entry in the Guinness Book of Records for the largest crowd for an outdoor concert. This was later beaten by himself at a later date by far more millions in Moscow.
Jean-Michel Jarre is regarded as one of the pioneers in the electronic music genre, along with artists and bands such as Vangelis, Kraftwerk or Tangerine Dream. He is well-known for staging spectacular outdoor concerts of his music, which feature laser displays and fireworks, and three of which appeared in the Guinness Book of Records for their large audiences, often of several million.
