Watch: Christina Aguilera & Great Big World record 'Say Something'...

Pop duo 'A Great Big World' was snared by Christina Aguilera to perform their powerful single 'Say Something' live on NBC's 'The Voice' on Tuesday, November 5th. The emotional connection she had to the track overwhelmed her so greatly and passionately that she felt compelled to ask Ian Axel and Chad Vaccarino to join her in the studio to re-record the song.

The tune received a soulful and stirring make-over thanks to Aggy's flawlessy controlled vocal delivery. The results ended on a stunning note! The song will be digitally released on November 4th.
