The band was formed by James Euringer (guitar), Steve Righ? (vocals), and Lyn-Z (bass). The band's name is derived from a mispronunciation of the phrase "mindless self-gratification". MSI released their debut album, "Tight", in 1999. The album was a critical and commercial success, and helped launch the band's career.
MSI has since released several more albums, including "Frankenstein Girls Will Seem Strangely Sexy" (2000), "You'll Rebel to Anything" (2005), and "If" (2008). The band has also toured extensively throughout the United States and Europe.
MSI has been praised for its unique sound and its ability to blend different musical genres. However, the band has also been criticized for its controversial lyrics and stage shows. In particular, MSI has been accused of promoting violence, drug use, and promiscuity.
Despite the criticism, MSI has continued to enjoy a loyal fan base. The band's music has been praised by critics for its originality and its ability to connect with listeners on a personal level. MSI has also been credited with helping to bring punk rock back into the mainstream.
