you gotta admit, if you know french, french vocals in trance are just killers!
there couple of track that i know: "dance avec moi", i think its my kosmonova, & "Syntone - C'est Syntone" kinda old...but still good.
if you know any other dish-em out...

I don't know much about french trance.
Actually I do know some french projects:
Absolum & Total Eclipse
(Both in the psychedelic and goa scene)
Have phun!

mm...absolom and total eclipse rocks my world...ohhh yeah. hehe. when i need it, the tracks by them make me trip out yo.

Rainbow Warrior - La Musique (Vocal Mix) is the first song to come to mind.

Celvin Rotane has put out several quality tracks. Most are somewhat old ('96), but still totally rock the crowd. You probably won't have a very easy time finding mp3s however...
