New Music: A Great Big World feat. Christina Aguilera – ‘Say Something’...

New York duo A Great Big World have recorded a new version of their track 'Say Something', featuring additional guest vocals from powerhouse diva Christina Aguilera. The sweeping ballad was made available to iTunes yesterday and she is set to perform it on tomorrow's broadcast of 'The Voice'. But did she deliver?
Yes, she sho did! Aggy pulls back from her excessive vocal acrobatics for a more subtle, heartfelt and vulnerable vocal delivery. It would be nice to see her utilizing this type of vocal control more often in the future. Her voice is gorgeous and she should consider going this direction for her next studio album!
