Mean Machine starred in the Tower Records "No Music, No Life" advertising campaign, and debuted in 2001.
Mean Machine was founded in 1998 by J-pop vocalist Chara, musician/DJ Chiwaki Mayumi, vocalist Yuki of Judy and Mary, saxophonist Yukarie of The Thrill, and actress Ayumi Ito.
[1] In 2001, Mean Machine released the single "Suuhaa," named for a kind of breathing exercise Chara learned when she was pregnant.
[2] A second single was released later that year, "Knock on You," reaching #38 on the Oricon chart.
The group was dissolved shortly afterward because of complications with the band members' solo careers.
