Christina Aguilera performs "Lift me up" live at the Hope for Haiti benefit.

Christina Aguilera gave a stand out vocal performance at the Hope for Haiti concert when she sung a stripped down version of ballad Lift me up from her Bionic album.

What I loved most about this performance was that Christina actually stuck to her natural tessitura (range). The result was a sublime performance that cut out the pushed and strained vocals she's has become synonymous with and instead gave us a chance to enjoy and appreicate the colour, texture and beauty of the voice.
