Kelly knows who she is, and that self-assuredness has raised expectations for her debut album, Tuesday's "Unbreakable Smile." Her debut album's lyrics paint a young woman who is unapologetically herself, in spite of her place in the pop-star industrial complex. (Kelly auditioned for "American Idol" in 2010, and shares the same manager as Justin Bieber.) But on Friday, she bypassed pop's typical smoke and mirrors — stage production, costumes, backup dancers. Instead, Kelly's vocals were the centerpiece.
