After winning American Idol in 2007, Jordin Sparks hasn't attained Carrie Underwood-level success, but she's fared far better in her pop career than Idol alums like Taylor Hicks. Her self-titled debut album featured two smash singles, "Tattoo" and a duet with Chris Brown, "No Air." Both songs showed that Sparks can put her DNA into material and helped the disc move more than 2 million copies worldwide.
Last year's Battlefield yielded the hit title-track single, which has very little to do with Pat Benatar aside from the fierce attitude attached. Currently, Sparks is prepping for her Broadway debut later this summer in the Tony-winning musical In the Heights.
Scrappy singer/songwriter Kate Voegle opens up, and it's safe to expect her heartfelt, acoustic cover of Leonard Cohen's "Hallelujah" — a strong reinterpretation of a track that has been touched by Jeff Buckley, Rufus Wainwright, and Justin Timberlake over the years.
