Aigrot says she’s proud of her work, except for one thing: she thinks she sounds a bit too much like Piaf. “I’m very blessed that people think it was Edith Piaf singing,” she says. “But it’s also difficult because I’m an artist. I have a career. My name is often in the dark.” Aigrot’s debut album, “Words of Love,” could change all that when it’s released next month. Or maybe not. It’s an album of more Piaf songs.
