Art-School got started thanks to the work of Riki Kinoshita, who got all of the members together. They started like any Indie band does, by playing at clubs and festivals. In 2002 the band was able to get a time slot to play at the Fuji Rock Festival. That same year, they also got a contract with Toshiba-Emi and released the single Diva that October. They wasted no time and released yet another work a month later. Their work paid off. In January 2003, they held a concert at the Shibuya Club Quattro that sold out! Art-School continued to sell out concerts that they performed at. In March 2004, a bassist and guitarist formally joined the band.
