Joey Cook thrilled the judges on Tuesday’s “American Idol” by auditioning with an accordion that complimented her voice quite awesomely.

The blue-haired contestant, a 23-year-old server from Virginia, played “Tallest Man on Earth” on her “squeezebox” as she sang, wowing the panel with her uniqueness, seen both in her unusual voice and her spunky personality. As she continued her performance, Connick whispered to his colleagues, “That could be on the radio right now.”

Keith Urban told her afterward, “Joey, that’s my favorite voice of the whole day. Seriously. We’ve heard some really good singers today.” Lopez agreed, saying to Cook, “You’re so unique and you look like a little doll.” Harry Connick Jr. went on to say, “I think you’re absolutely terrific. I love you. I think you’re wonderful.”

Connick did have one critique, though, saying he wanted to “caution” Cook to not become a “novelty” performer. “But you’re very talented, for sure,” he added. In fact, the judge continued to gush after Cook left the room. “Like, how many times have you seen that but an effort to be that?” he said to Lopez and Urban. “She’s legitimate, that girl. That’s cool.”

Cook was one of a group of contestants selected to audition for the trio in Kansas City, Missouri, after first trying out via the “American Idol” bus tour.

When not working, she’s playing her favorite instrument, the accordion. Her grandfather has always wanted her to audition for American Idol.Without much hesitation, the judges agreed to send an ecstatic Cook to the next round of auditions in Hollywood. AWW will keep you updated on the results.
