Marietta's Angie Keilhauer passes 'The Voice' battle rounds

Unfortunately, Angie suffered the dreaded "montage," meaning the show only showed a clip of her battle. That doesn't bode well for her future on the show because it meant the editors found her battle among the less compelling ones. (They had nine to feature and showed six in full over two hours.)

And sadly, NBC does not release the full battle rounds that don't air so we'll never see the actual performance. Angie, in an interview after the battle rounds aired, felt especially bad for Teresa since she was also montaged for her original audition and got virtually zero air time. At least Angie's blind audition was featured.

"What's cool about the show is it doesn't foster a competitive atmosphere," Angie said. In fact, she felt truly bad when Teresa was cut. "It was a bittersweet moment we both couldn't move on," she said.

The 24-year-old Pope High School graduate, in an interview after the blind audition, said she had a hard time picking her coach out of the three judges who turned their chairs but was drawn to Blake given her country background.

She had planned a country album before joining the show and though Blake could help her out the most. "His music I grew up with," Angie said. "It means something to me. His songwriting is something that is really valuable. I couldn't see myself saying no."

The original arrangement of her initial blind audition song by Dierks Bentley didn't include parts she liked so she changed the arrangement more to her liking. "I worked with a vocal trainer and we created this new version," she said. "They were really flexible."

She joined the cruise ship world two years ago on a whim. She was so unprepared, she walked on the wrong cruise ship at first, holding a duct-taped duffel bag. "I was not a real artist," she said. "I had nothing to lose."

Angie said the schedule was brutal: four one-hour shows a day. That did a number on her voice and she got polyps. She had vocal surgery and stayed home in Marietta. "That moment changed me," she said. "I realized how much I loved my family. My sister got in an accident and needed someone to take care of her. Fortunately, I was there and not on a cruise ship."

It also gave her time to audition for "The Voice." They had found her from YouTube videos she did on the cruise ship during her downtime. "Opportunity comes with persistence," she said. And the surgery made her voice significantly better. "I can hit at least a full octave more than I did before," she said.

She said in an interview after the battle rounds that she took a risk with her knockout round song. This was pre-taped so she also knew what was going to happen but couldn't tell me.
