Watch: Christina Aguilera keeps it low key for ‘Say Something’ on ‘The Voice’...

After Monday night's messy vocal showing, Christina Aguilera somewhat redeemed herself when she assisted pop duo A Great Big World for a performance of their new single 'Say Something' on 'The Voice' last night.
A more minimalistic approach was taken for the world premiere performance. A stark contrast from the glitzy, 'Burlesque' style performance the other night. Aggy's vocals were subtle enough to a point where she didn't bust any ear drums this time. Phew! Singer Ian Axel sat at a piano crooning out most of the track before Aggy comes in. The song is currently out now on iTunes. Check out the first live performance inside!
