The 5.6.7.8's are a Japanese all-female rock and roll group with a heavily surf-influenced garage rock sound. The band was formed in Tokyo, Japan in 1986; its current lineup consists of founding members Yoshiko 'Ronnie' Fujiyama (vocals, guitar) and her sister Sachiko Fujiyama (drums), and long-time bassist Akiko Omo. The derivation for the group's name is their sizable repertoire of rock and roll covers from the 50s, 60s, 70s, and 80s. Already well known in their homeland, the group first achieved international cult fame as a result of an appearance in the 2003 film Kill Bill Volume 1. Read more about The 5.6.7.8's on Last.fm.
