Ooh, shit - Benjamin Biolay is excellent, most of the time. Get 'Home', a collaboration with Chiara somebody.
Another female vocalist - Coralie Clément (Salle Des Pas Perdues) - nothing amazing to my mind, but certainly not bad.
Paris Combo ain't anything special IMO but someone might like em.
Lhasa, album 'The Living Road', ain't French herself but some of her stuff is, and it's all good.
There are a few Putumayo Presents compilations like Paris, French Cafe, who knows what else.
Raphael is supposed to be popular but I just find it really average.
That's me done I think.
