Ariana Grande Performs 'Bang Bang' in Tron Outfits
Ariana Grande at 48th Annual CMA Awards in Nashville.

Wearing neon-lined outfits straight out of the virtual world of TRON, Little Big Town took the stage at the 2014 CMA Awards to deliver a rousing version of "Day Drinking," a performance immediately followed by Ariana Grande singing her Nicki Minaj/Jessie J collabo "Bang Bang."

But since Minaj and Jessie weren't at the CMA Awards, Little Big Town pitched in on the "Bang Bang" vocals. Incidentally, Grande also wore a color-changing neon outfit, although hers was more Jem & the Holograms than TRON.
