Foxes Mashes-Up Pharrell's "Happy" With Massive Attack's "Teardrop"

If any nascent pop star can collide two very different atmospheres into one warm-blanket of a mash-up it's the U.K.'s breakout artist of 2013, Foxes. For her latest Radio 1 Live performance, Foxes blends Pharrell's hit "Happy" with one of the biggest electronica singles of the '90s, Massive Attack's "Teardrops." 

The result is chilling. Bet you never expected to hear "Happy" sound like this!
