The Yellow Monkey
Yoshii's first band was Urgh Police, which he joined in 1986 as bass guitarist under the stage name "Robin". After releasing a demo, an EP and one album, they disbanded. In 1988, Yoshii switched to guitar and formed a new group that included Youichi Hirose and Eiji Kikuchi, where he used the nickname "Lovin". When their vocalist left, Yoshii took over that position and recruited Eiji's brother Hideaki as guitarist. The Yellow Monkey had what is regarded as their first concert on December 28, 1989 at Shibuya La Mama.
