Bea Miller's big performance of I Wanna Know - her collaboration with NOTD - becomes a real showstopper in Michael Baldwin's impressive video.

There's nothing new about a singer being multiplied courtesy of motion control, but when it works well its always mesmerising - and that's the case here. As clones of Bea Miller start appearing in a warehouse space, Baldwin ratchets up the intensity of her performance, and the video. 

MICHAEL BALDWIN:

"This track is going to be HUGE. When I first heard it, Bea's vocal was so powerful that it felt like she was getting more and more distressed as the track went on. That made me think of more and more of Bea. So, armed with an idea that was way out of the budget we had, it was time to twist arms and pull favours in every direction (what's new!).

"Somehow it all came together just about in time for the shoot. It would have all fallen apart though if it wasn't for Bea's incredible screen presence and absolute commitment on the shoot. She had to be everywhere. Literally. All day. She blew us all away as soon as she began performing and kept that energy up until we finally wrapped in a grim, feezing cold, windy car park somewhere near Dagenham late at night.  A long way from LA, which is where we would have all preferred to be to be honest."
