The Twelve Dreams Of The Sun was a concert held by musician Jean Michel Jarre on the Pyramids of Giza, Egypt starting on December 31, 1999 and carrying overnight to January 1, 2000.
 It was attended by 120,000 people.
 The concert consisted of two parts, the Main Concert and a Sunrise Concert.
 The concert cost approximately $9,500,000 and it originated when Jean-Michel Jarre was contacted by the Egyptian president Hosni Mubarak with a special project to celebrate the dawn of the new Millennium at the foot of the only remaining monument of the original 7 Wonders of the World - the Great Pyramids.
Se Alli Diastasi is an album by the Greek singer Mando.
 It was released in Greece in September 2000 by Sony Music Greece.
 The album is more pop than Mando's previous one, with many western type songs.
 Hits of the album include "Akoma Mia Fora", "S'Efharisto" and, the most successful one, "Pio Poly", with music by Mando and lyrics by Natalia Germanou.
 The album also includes "Fos" (Ask), a duet with Sertab which is one of Mando's most notable collaborations.
 Jean Michel Jarre gave his permission for the first time for a rendition of one of his songs, as he was impressed by Mando's vocal abilities when he listened to her demo tape.
 Mando’s performance in "C’Est La Vie", first sung by Natasha Atlas, was liked so much that Jarre gave Mando not only his permission, but also his original arrangement of the song.
Les Concerts en Chine (English title: The Concerts in China) is a live album by Jean Michel Jarre, recorded in 1981 and released in 1982 on Disques Dreyfus.

 For a period of time, it held a place in the "Guinness Book of Records" as the largest outdoor "rock concert" in history, with figures varying from 1 to 1.5 million in attendance.
 Rendez-vous Houston is remembered for being the concert which celebrated the astronauts of the Space Shuttle "Challenger" disaster, which had happened only two and a half months earlier.
 One of Jarre's friends, astronaut Ron McNair, had been killed in the disaster.
 He was supposed to play the saxophone from space during the track "Last Rendez-Vous"; his substitute for the concert was Houston native Kirk Whalum.
Live From Gdańsk (Koncert w Stoczni) (pol.
 "Shipyard Concert", referring to Gdańsk Shipyard) is a live album by Jean Michel Jarre, released in 2005, exclusively in Poland.
 It contains selected songs performed during Jarre's Space of Freedom concert in Gdańsk, Poland, on 26 August 2005, commemoraiting twenty-five years of the Solidarity movement.
AOR was a performance by Jean Michel Jarre.
 Jarre became the youngest musician to see one of his works played at the Paris Opera, at its reopening on 21 October 1971.
 The reopening consisted of three ballets; the first and third ballet were set to classical music, AOR - the second ballet that night - was completely electronic.
 It was the first time that electronic music had been allowed to be used.
 Jarre even had to paint the speakers of his synthesizers gold to match the decor of the opera house.
 There he performed with the Paris Opera Ballet, choreographer Norbert Schmucki and musician Igor Wakhévitch, who co-wrote the music.
"La Cage" is the 1971 debut single by French electronic musician and composer Jean Michel Jarre under his own name.
 Although produced in 1969, Jarre was unable to find a record label that was willing to release the single due to its experimental sounds.
 After a few rejections, he found Pathé Marconi willing to release it in 1971, but the single turned out to be a commercial failure, with only 117 copies sold.
 Pathé Marconi destroyed the remaining stock.
 However, the master tape of "La Cage" was preserved, and as a result the song was featured on the compilation "Made in France" in 1978.
 The single can also be found on the "Rarities I" bootleg compilation in 1994, while the rhythm of "Erosmachine" was reused throughout the track "Chronologie 2" from his 1993 album "Chronologie".
Odyssey Through O is an album by Jean-Michel Jarre, released in 1998.
 It contains remixes of tracks from Jean Michel Jarre's "Oxygène 7–13" album, as well as the "Rendez-Vous 98" single.
 It also contains a computer program, JArKaos, a scaled down version of the ArKaos software used by Jarre to produce visual accompaniment to his music at concerts.
 JArKaos allows users to manipulate visuals using their computer keyboard while listening to the album.
