Alicia Keys [ tickets ] seamlessly wove her piano-playing Grammy prowess with music while celebrating the 1930s during her two-hour performance Friday (3/11) at Phoenix's Dodge Theatre.

Dubbed "Uptown Saturday Night," the show took the sold-out crowd back to an era when the likes of Cab Calloway played in intimate jazz clubs. An emcee wearing a white suit and hat welcomed the audience, apologizing for his inability to get Ella Fitzgerald or Calloway to play the show. Instead, he offered up multi-Grammy winner Keys.

"She can sing and she's pretty, too," the host said with a lecherous laugh. "Everyone give her a 1931 welcome for that Ms. …. What's her name again?"

As the audience responded with "Alicia Keys," the curtains revealed the elegant stage draped in white curtains with posters of Calloway and Keys, affecting Fitzgerald, on a back wall. A crystal chandelier was the focal point atop the stage.

Taking center stage, Keys kicked off her show with a shuffling, '30s-inspired take on her hit "Karma," from the album "The Diary of Alicia Keys." She strayed from her trademark piano for most of the show, instead utilizing the entire stage much in the same way a rock performer would. The audience was not disappointed, although they did cheer wildly when she hit the keys.

In between songs, she did mid-tempo dance numbers with her white-garbed back-up singers. While the dance numbers didn't mesh well with Keys' performance, the crowd did not seem to mind. She ended her soulful rendition of "Heartburn" by collapsing on a red chaise as her background singers fanned her with black feathers.

In keeping with the evening's theme, Keys and her background singers delivered an updated version of Calloway's "Minnie the Moocher," one of the highlights of the concert. She turned it around quickly, adding a few lines from her Usher collaboration "My Boo."

The pop and crackle of a 45 record snapped through the speakers as she played the opening lines of "If I Were Your Woman," during which she manned the piano.

Keys underwent a handful of costume changes during her two-hour performance. She hit the stage wearing a silky black pant suit with a plunging neckline. She was dripping in diamonds, sporting a sparkling broach, earrings and bracelet. Keeping with the 1930s flavor, she wore a white feather in her hair for effect. Toward the end of the show, she changed into a beige slinky dress and elaborate head dress for a series of hits.

Feathers seemed to be a source of inspiration for Keys. As she finished "A Woman's Worth," she playfully pulled a feather boa from a coat rack and whipped the accessory to the ground.

Keys was not the only star in the theater, however. The opening act, John Legend, lived up to the expectations placed upon him by the media and hype machines. A Kanye West protege, Legend coolly serenaded the audience from behind a keyboard with his soaring, inspiring vocals.
