DESCRIPTION:
Tiffany said to me, I want to do this David Guetta tune featuring Sia, it's called Titanium. I listened to it and said, sure. We sat down, hammered out this arrangement, and played it for the first time at RockbarNYC early in 2013. Being twins is an honor all its own. Sharing the stage when we get to do stuff like this? Icing on the cake!

Special shout to Sara Z for video-ing this. :)
