A couple of weeks back, we were left in awe by the beauty that was the acoustic version of Zedd's "Clarity." It's one thing to hear that an artist is classically-trained; it's another to actually see them translate their music so delicately.

Joined by Foxes (with Alvin Risk on background vocals) and a string ensemble, Zedd made his national television debut on Letterman, a feat that no other EDM artist has achieved.
