Katharine shined last night with "Over the Rainbow" but here other two songs didn't work as well. I could see her getting voted off, but I think that Elliot was off key in places on all of his songs. He seemed to be better at the beginning of the competition, but maybe that was because we had worse singers to compare him to. Taylor kicked it last night and I think he was the clear winner of the evening.
Overall, I think Katharine has the best voice of the three remaining contestants, but she doesn't have the confidence to let her voice out naturally. As the judges have commented she pushes too hard and over sings some of her songs. I think she'll be better after the show is over, but unless she does some interesting songs, I doubt I'll be listening to her.
Taylor is a very good entertainer. He is more than just a singer. Sometimes he lets his entertainment side get the best of him and lets his vocals slide, but he's never boring. I think it will be interesting to see what comes out of him when he's in a recording studio and can sing without having to perform.
I hope the final is Katharine and Taylor, but I could see Elliot make it in the final with either of them.
