What happens next is so delightfully strange and entertaining. The music comes on, and it’s Meghan Trainor’s, “All About The Bass.” The light show starts, the audience quiets down, and Cristina and the dancers appear on the sides of the stage. They are identically dressed as Cristina, except they are wearing short blonde wigs.

They dance around for a minute, setting the tone for their big reveal. They come together to link arms in the center of the stage, and this is where the real performance starts. It’s hard to understand what’s happening at first, but stick with it, and don’t move your eyes! This is a clever idea.
