It's American Idol Season 11's Top 13 Performance Night tonight (Wednesday night in the U.S.) and the batch will tackle Whitney Houston and Stevie Wonder songs.

Those expected to make strong performances are last episode's top performers, led by Jessica Sanchez and Skylar Laine. Among the boys, it is hard to tell whether early favorite Phillip Phillips could pull a Stevie off, having seen him to be inconsistent during Hollywood week. Phillips was pretty strong last week, so if Phil could give a strong number tonight, it would only go to show that he means to win big this season.

Not much is expected from the adorable Heejun Han, but his fans have reason to worry. While he was among the voters' Top 10, his performance last week was not particularly strong. It was not nearly as memorable as his funny one-liners, and it was miles away from his Pittsburgh auditions. So how much farther could Heejun Han go?

Next to Phillip Phillips, whose name is starting to bear a cute ring to it (instead of making an annoying sound), Joshua Ledet could also do well. Afterall, Joshua does not give a mediocre performance, at least not since his auditions. If he chose his materials carefully, he certainly could do justice to a Stevie Wonder song.

Who will deliver stunning performances tonight? Will the judges deliver comments that the audience could reconcile with their own?
