Now, solve this: Passage: Asian Kung-Fu Generation was first formed in 1996 when Masafumi Gotoh, Kensuke Kita, and Takahiro Yamada met while attending a music club at Kanto Gakuin University, a private university in Yokohama, Japan. After realizing that they all shared similar musical tastes, the three decided to start their own band. Masafumi Gotoh became the lead vocalist and played rhythm guitar, Kensuke Kita played lead guitar and sang backup and Takahiro Yamada played bass. Drummer Kiyoshi Ijichi joined them later on after parting with another college band he was in. The four then began providing performances at their university as well as throughout the local Yokohama area. After graduating from college, following years of playing in several small venues and having collaborated with fellow Japanese rock musician Caramelman, AKFG released their first indie EP in 2000. The six-track EP contained original lyrics written and sung almost entirely in English. The four spent the remainder of the year playing in clubs and hosting independent events.
