The first part of this album is for me the most beautiful jewel WYD has ever composed. 18 minutes of escape in the magical musical world of this Impressionist sound. The heady rhythmic melody of the beginning gives way after 6 minutes a planing unreal atmosphere where synthetic routes intermingle, sounds passages of jets and strange sounds of all kinds, above it all a planing melody giving a great depth to the whole. Welcome Jarre galaxy! A final passage of air sweeps everything and made net start a third subpart again leaving us very rhythmic hypnosis! Other memorable passages are noted later in the album, like the shattering final point of the fourth part, the sound of a train going at high speed out of nowhere, eclipsing the net drum. What happiness!
