In June 2008, a project "Fasten Musique Concrete" launched in the center of club music world, London UK. Now the project has landed in Tokyo since February 2009. It brought fresh new style of parties to Tokyo, such as a party which is held in 2 cities in different countries, rooftop party, boat party, beach party, and casual lounge party, achieving remarkable successes.
