Because December 21st, 2012 isn’t over quite yet, there’s no reason to throw away those “End Of Days”-themed party hats. Derek Smith, aka Pretty Lights hasn’t. Today the electronic artist shared a six-minute mashup of doomsday-sounding tracks from folks like R.E.M., The Doors, and Black Sabbath. Originally performed at a New Year’s Eve show last year, Smith dug up the mix for today’s occasion, commenting on his Soundcloud, “I love life. I wanna keep it going!”
