Rendez-Vous (1986) is probably one of the most overlooked of the albums from both a Jarre fan and non-Jarre fan's perspective, regardless that it is an essential album in the catalogue.
Listening through headphones, take a listen to track 1, which is probably one of the best introductions to an electronic CD, being only a short track and then straight in to one of the most popular and magically performed Rendez-Vous II (Second Rendez-Vous, track 2).
I believe it's one of the best orchestral, but electronic pieces ever conceived. If you went to see Jarre live, you'd pray for Rendez-Vous to be played. It's also the debut of his famous Lazer-Harp, in which (live on stage) several lazer beems are generated, facing to the sky and then mirrored over the audience, and breaking a lazer generates a note.
The 'Lazer-Harp' sound that is used in Rendez-Vous II (& III) and future tracks is ground-shaking.
Rendez-Vous is really the anthemic of all the albums - it's powerful and makes a massive statement.
It takes a serious listener, even though it's an album you can listen to in the background to an extent, but can only be fully appreciated when you give it undivided attention. Do this, and you will be blown away.
Other important parts to note are:
Rendez-Vous IV: Made more famous as ITV's (UK) World Cup theme for 1998 and a very popular track of Jarre's...
The album also has a tribute to Ron McNair (and the other 6 astronaughts who died in 1986)...
Overall, despite the album not being a complete dream, there are tracks that have set a new standard for Jarre, and tracks people love. Rendez-Vous II & IV being the popular, and without this album, Jarre would not be as popular as he still is today.
