Metropolis

This song is a collaboration between David Guetta and Dutch newcomer Nicky Romero, who attained a joint residency with the French DJ/producer at party hot spot Ibiza for the summer of 2012.

Mr. Brainwash, who is a Paris-born Los Angeles-based street artist, directed the song's music video, which was filmed in an art studio space at London's Sorting Office. Discussing how the pair met, David Guetta explained: "[Mr Brainwash] was totally crazy, following me around everywhere and I didn't know who he was. Years later I was on a plane watching a movie about street art, and it was his movie!"

Mr Brainwash's real name is Thierry Guetta, but the street artist isn't related to the French DJ.

This wasn't Mr Brainwash's first foray into the music world. He also created the cover for Madonna's 2009 hits compilation, Celebration.
