So I tihnk David Garibaldi is the one to watch tonight. The only other act that comes close (literally) is William Close and his Earth Harp. This act reminds me a lot of The Blue Man Group only with a giant harp instead of drums and percussion. It could be a toss-up between the two Davids tonight.
Then there's the Untouchables. Call me cold hearted but I don't believe these children belong in the finals. The boys and girls combined dance group is talented but I'm not sure anyone would pay to see them in Vegas. It is kind of like paying to see other people's kids do impressive things. You would pay to see your child do something incredible but wouldn't always pay to see someone else's. Did you know that the dance group almost got kicked out of their hotel for being loud and obnoxious? Yeah that's what you can expect from them on tonight's show.
