Very different and experimental, very good too. When I was a kid, PLD Ethnicolor somehow scared the shit out of me, so I didn't like that track much then. I listened to rest of the album pretty much (and usually the later half of Ethnicolor), I really liked the music. And still do.
Unlike then, my ultimate favorites are Ethnicolor (perhaps my most favorite Jarre track ever, in fact) and Zoolookologie. I admit I don't listen to the rest of them that much, except when I have my Zoolook listen-a-throughs.
I can do this and not feel bad at all too:
