Crystal: She was correct to choose a "smaller" song this week cuz she's got to provide some variety on that stage after many weeks of competing. Crystal did a good job with it, though the pacing was awkward at points. Crystal was clever in assembling the band behind her, looking like she had traveled with them for years. She had a short duo performance with her one female backup singer, and that was cool, too.
Siobhan: I actually liked the singing, but the dancing and running around was distracting.
Lee: As usual, loud squawking and off key. And his timing was off, too, making it impossible to enjoy the rhythm and melody of the song.
Mike: Fantastic voice but boring.
Casey: Serious rock/pop artist and excellent performance, but a boring song. I agree with TopCat, the visuals were awful with him sitting in the middle of the audience. A ballad like requires that the focus be only on the performer. Casey should never have shared the stage with dopey chicks in the audience.
Aron: I remember hearing his pleasant voice while I was falling asleep. I honestly don't remember the performance.
