Carousel was a project by Gorillaz that eventually became their third album, "Plastic Beach". Recording sessions as part of Carousel commenced from June 2008 to November 2009 before it was eventually scrapped and then turned in favor of becoming "Plastic Beach" in 2010.
Outside of the tracks that can be found on "Plastic Beach", only a few select tracks were thought to be a part of the Carousel recording sessions. One such track is entitled "Electric Shock" and was debuted in demo form on BBC Radio during a Damon Albarn DJ session in January 2009, a little over a year from Plastic Beach's release in March 2010. The other demo tracks that debuted at the radio show (and can now be found on "Plastic Beach") were "Stylo" and "Broken".
