Here is Christina Bianco's version of "Let It Go" from the movie Frozen. I think she does an INCREDIBLE job hitting the nail on the head for EACH person. If you are familiar with any of the people she imitates (i.e. Britney Spears, Christina Aguilera, etc), then you will UNDOUBTABLY enjoy this video!
Here is the second version. Also, exceptional, but not for the same reason. It is a beautiful mix of sounds and cultures, and this girls voice is UNBELIEVABLE!! Very cool vibe!!
