IMHO, this is one of the best and most diversified tracks by Jean-Michel Jarre. The 10 minutes opener of "Chronologie", the concept album based on Stepen Hawking's book "A Brief History of Time", is a flushing specimen of electronic & symphonic music.
"Chronologie" was the tenth studio album by Jarre.
The tempo changes and the intricated keyboard interplays are among the best features of this instrumental, and Jarre also offers one of his best melodic works ever. Each theme is well exploited and well entwined with the rest of the composition. Last but not least, the fusion between rock instruments and electronic devices is perfect and gives a deeper soul to this track. Epic. In all senses.
