Derek Vincent Smith, aka Colorado-based electronic musician Pretty Lights, recently dropped this rolling, uplifting new track, "We Must Go On." To mark the release, Smith and his girlfriend, visual artist Krystle Blackburn, put out this video chronicling their travels through 2011. Shot on a pair of Canon 7Ds with about six lenses, the clip documents their ramblings through London, Paris, Warsaw, Oslo, Vancouver, Prague, Auckland, Sydney, and across the United States (New York City, New Orleans, Detroit, Denver), and more. The vid is a collage piece, showing the collective human experience of life in the city.
