On the cover of her latest album, "Un Dia," Juana Molina's face is distorted beyond all recognition; the effect is both intriguing and disturbing.

"If it's your face (on the album) you would like to be pretty," the singer/songwriter tells me over the phone from her home in Buenos Aires. "But once you have that pretty image, what's next? It's boring."

On all of her five albums, her face is unrecognizable, and this is a little act of rebellion against her past: Molina used to be a famous comic actress in Argentina.
