Why Mylene Farmer sometimes compared to Kate Bush?

1) "From the 1980s onward it has become almost standard for individualistic female singer-songwriters to be compared to Bush by the media. She has been noted as an influence on artists as diverse as Amy Winehouse, Alexz Johnson, Antony and the Johnsons, Björk, Bloc Party, Coldplay, Goldfrapp, Milla Jovovich, Joanna Newsom, Mylène Farmer, KT Tunstall, Lily Allen, Muse, Elisa, OutKast, PJ Harvey, Darren Hayes, Tori Amos, Little Boots, Kate Nash, Florence and the Machine and Bat for Lashes."

2) "I know several Kate Bush fans who like her, but I don't think they are comparable (as usual). I also know one Kate Bush [fan] who doesn't like her. (uli@zoodle.robin.de)
Both Mylène and Kate Bush like theatrical live shows, but that is where the comparison ends. Mylène tends a lot more towards the pop and dance front, although her lyrics are rather melancholy most of the time. (marcel@kimwilde.com)"

"She's been called the French Kate Bush by the local press, probably for the live shows which I understand are very theatrical."

"In France, Mylène is a true megastar, her fame in that country is comparable to Madonna elsewhere in the world. Musically and visually she compares well to Kate Bush. Just like Kate, she releases a studio album every 3 to 4 years (the same tempo Kate used to work in), and her live concerts are visual spectacles."

"Mylène also writes of phantoms and the sinister god of time (who points his finger and beckons us to follow). The French Kate Bush? I wouldn't say she's quite that literary. But with such dark poetic imagery, I'd say she very well may be the French Happy Rhodes. She has a soft soprano voice and a flawless diction. Do you have to understand French to enjoy her work? No, but it would help to have a working knowledge of the language to feel the irony in her delivery. For here is a woman who clearly relishes the opportunity to dwell in her soul's darker corners. Without the life she seems to eschew, her ecstasy would be ended."
