WINNER: Imagine Dragons
Rock bands never get a lot of time to shine at awards shows dominated by pop music these days, so Imagine Dragons knew they had to create a memorable moment at the AMAs — and they did. The Las Vegas crew started their performance with "Demons" before slipping into their megahit "Radioactive," which was punctuated by an all-out drum frenzy. Almost every member of the band dropped everything, grabbed a mallet, and started pounding away at a visually appealing array of massive drums set up around the stage. The result was a little tribal and a lot impressive.
