'Captivating' Kez Ban surprisingly advances on 'American Idol,' as does Johnny Keyser

"You are a star, in my opinion," says Mariah Carey. On he goes to Hollywood.

Hmm, singing an original song; has a surprising good voice, definitely a ministrel quality to it, unique with a great tone. Plays the guitar well too; she's a natural performer. Might be too weird for this show, but she can sing and is interesting as heck. Judges all listening quietly. 

"I like you, very interesting," says Jackson. "I can feel the realness in you," says Carey. "You're very captivating," says Minaj, which is the exact right word.

She says afterward she's "in total shock" she made it to Hollywood.

"I had a feeling that it was possible, but I just thought I was too bizarre."

"If you had the right vocal coach, you could do a lot with your voice," says Nicki Minaj. She then insists on singing again, even though the judges try to stop her.

"You can't do that," says Minaj, "that's a weapon right there!"
