G.M.S. began when "Riktam" and "Bansi" met in high school at age 14 in Amsterdam. Both were passionate about electronic music and the duo chose to leave school and seek their education in the club scene. Even though they were too young to legally enter a nightclub, Riktam and Bansi began spinning at clubs in Amsterdam. On most occasions, they had to be whisked into the building's side door to avoid scrutiny by the authorities.
