Daniels graduated from CCM in the spring of 2001 and spent that summer with Pittsburgh Civic Light Opera, performing in the ensemble alongside another newcomer named Alexander Gemignani, who's now Les Miz's Jean Valjean. Her CLO shows included Bells Are Ringing, starring Victoria Clark; South Pacific, starring Sutton Foster; and Company, starring Malcolm Gets—who was her fiancee Sir Evelyn Oakleigh in Anything Goes last summer.
She was cast in her first Broadway show, Aida, only a month after she moved to New York. But it was a bittersweet moment: She got the news on Sept. 12, 2001, a few hours after her callback—a callback that had originally been scheduled for the day before. "I was walking up my stairs—I can picture it now, I was in a fifth-floor walkup—after coming back from rehearsal," Daniels recalls about getting the Aida job. "I didn't think I'd gotten it because they didn't ask me to sing a solo that they asked another girl to sing. Then I got the call, and I just collapsed in the stairway and started crying. Probably from the emotion of the day before, but also it's my Broadway debut!"
She dropped out of the show she'd been rehearsing, Lady in the Dark for Philadelphia's Prince Music Theater, for Aida, where she played Nehebka and understudied the title role (she would later do the same on the tour). Her next role—only her second in New York—was Clara in New York City Opera's early-2002 production of Porgy and Bess. For about three weeks, she performed in Aida while rehearsing Porgy and Bess—"a huge challenge vocally," but it became "one of my proudest accomplishments," she says. "There I was, like 22, right out of school, singing 'Summertime' at Lincoln Center."
Later that year she did Ragtime at Massachusetts' North Shore Music Theatre and Dorian, a jazz musical adaptation of The Picture of Dorian Gray set in 1980s New Orleans, at the Denver Center. The following spring she was back on Broadway in the Bacharach revue The Look of Love—oh so briefly, as the critically lambasted jukebox musical ran for only a month and a half. But she did get to cover for Liz Callaway at several performances, soloing on "Alfie," "Knowing When to Leave" and "I Just Don't Know What to Do With Myself."

In the fall of 2003, Daniels went into the Nine ensemble when John Stamos and other replacements joined the cast. In 2004, she was a vacation swing for the Little Shop of Horrors Urchins on Broadway (and later on tour) and reprised her Dorian role—Celia, based on the novel's Sybil character—in a new production of the show, featuring Max Von Essen, at NoHo Arts Center in Los Angeles. That summer she starred as Belle in Beauty and the Beast at North Shore, and she did Beauty with the same principal cast and creative team again the following year in Sacramento. During that run, Daniels sang the national anthem at a special event at the California Museum for History, Women and the Arts attended by Governor Schwarzenegger and his wife, Maria Shriver. She met them and afterward received a thank-you note from Shriver's office.
By the end of 2005, she was again performing in Northern California, in the San Francisco tryout of Lestat. The Elton John vampire musical bowed on Broadway last spring—and, like Look of Love, closed within weeks. It hurt a little more this time, since Lestat was an original musical and she'd been with it much longer, through cast changes and rewrites. "When you're in a show, it's hard for you to look at it objectively," she says. "You're a part of it and you start to brush aside the things that are maybe problems, because you have to believe in your projects." She chalks it up as "a good learning experience."

She was able to rebound quickly from the Lestat failure, because she'd been cast in Anything Goes before its closing notice was posted. As Goes' Hope Harcourt, Daniels had a happily-ever-after, albeit not with the man to whom she's engaged at the beginning of the play. That hasn't been the case with many of her other roles: Fantine, Clara, Nehebka, Sarah in Ragtime, Dorian's Celia all die. Daniels even died in her first speaking part, Ti Moune in Once on This Island in high school. It was also in that role that Daniels started to refashion her theretofore classically trained voice. "I didn't learn to belt, musical theater-style, till high school," she says.
After moving from Louisville, Ky. (where she was born) to the Nashville area to Rochester, N.Y., Daniels' family had settled in Atlanta as she was starting high school. They lived in suburban DeKalb County, and she attended its public performing arts magnet school, Avondale. Daniels had only just discovered theater; since age 5, she'd been concentrating on instrumental music, first piano and then flute. She gave up those instruments, plus basketball, track and cheerleading, after seeing her junior high's production of The Wizard of Oz. "Oh, that looks like fun," Daniels remembers thinking. "I was really inspired by the girl who was Dorothy—'I want to be good like her.'"
Among her fans, Daniels has become identified with a Dorothy song—not from The Wizard of Oz but The Wiz. She first sang "Home" at her high school senior showcase for prospective agents in NYC and often sings it, sometimes by request, in concerts and auditions. "It's definitely a part I would like to play before I'm too old," says Daniels, who auditioned for last fall's highly lauded revisal of The Wiz at La Jolla Playhouse that has stirred speculation about a Broadway production.
She has already scored a television credit. Daniels filmed a musical sketch for Chappelle's Show, a spoof of the Virgin Mobile commercials where people sang their phone conversations to each other. The series was canceled, due to Dave Chappelle's mental health hiatus, before her piece aired, but it's among the bonus features on the Chappelle's Show: The Lost Episodes (Uncensored) DVD. In it, Daniels informs her boyfriend (Chappelle) in song that she's pregnant and even drops a melismatic "motherf---er" when he tries to bolt.
She hopes more TV parts are in her future—and maybe a return to the opera house. Doing Porgy and Bess took some adjusting for someone used to the theater world. "The conductor seemed to be more in charge than the director. It was much more about the music and the singing of the music," says Daniels, who was in the "C" cast, which mostly did matinees. "We never had a run-through on stage, we were just expected to know it by watching the 'A' cast in rehearsals." Among other differences from the theater: "Stage management was not as involved in the running of those things as they would be in an Equity show. Also, when I went on as Clara, a makeup artist did my makeup. Normally, in a Broadway show, unless you take special makeup, you do your own."
She may wait to give opera another shot. "With opera singers, your voice doesn't really mature until you're older," says Daniels, who admits that most operas don't grip her the way musicals do. "I could never get through a whole opera [watching on TV]; I would get bored. If it's not keeping my attention, maybe it's not what I need to be doing. But I do feel like, since I have the ability to sing like that I shouldn't waste it and not use it at all. So it's something I'll maybe look into in ten years or so."
