Yelle is a French singer who's name has been mentioned a few times in the past in here who've performed in the U.S.
It was mentioned in chat that the French market is a fickle market for French singers and I think this is a close enough thread to talk about it. It's been discussed in the past that younger people in France seem to prefer the main stream artists like Beyoncé, Rhiana, Lady Gaga, Madonna, Katy Perry,etc. On one of my trips to France, I asked a young man to name some of his favorite female singers and he rattled off several names, but not one of them was a French singer so it does seem French female singers in France and the same is probably true of male singers seem to be at a disadvantage in France.
