Overall, I think Chris and Katherine were the best singers last night. Chris's performance was helped out by the special effects and it made it seem like a rock concert. I noticed the Katherine/Kelly Clarkson singing comparison early on, but there's something about her personality that bugs me a bit.
Other singers:
Ace - I thought he was terrible. Sorry SB!
Pickler - I agree with SB. zzzzzzzzzzzz
Elliott - This guy is a great singer and if he had a tiny bit of personality/back story, he should be one of the favorites.
Mandisa - Has trouble when not using her power voice. That's why she did well with "I'm Every Woman" - the whole song was in power voice. Not one of her best performances but still good.
Bucky - Did OK.
Melissa - Terrible. My pick for first person out.
Lisa - Still trying to find her niche with her great voice.
Kevin - I agree with JG - he's getting a bit cocky. You know it's bad when I'm watching thinking "Why is this guy on my TV???"
Taylor - Taylor is just fun to watch. Got the longest and best ovation of the night.
Paris - Reminds me of Fantasia. Still waiting for the breakout performance. Very good last night.
