So here's the whole story: First Jamie Reynolds of the Klaxons wa sintroduced to Crystal Castles by a friend. He in turn told his friend who was just starting a new label called Merok. Merok first release was "Atlantis to Interzone" by Klaxons and then "Alice Test" by CC was their second. Later Klaxons would call Ethan to do a much-blogged remix of "Atlantis". In true Crystal castles form, the intro samples stayed in his sampler and became the basis for a new track. Alice wrote lyrics to it and it has become a part of their set.
