Starting the Slits in the late '70s at age fourteen, Up served as a radical, influential voice to a generation of male and female musicians alike. Vocal about the fact that the group's dub-heavy, minimalist punk sound wasn't politically motivated, Up never denied that she was a spokeswoman for feminism in the music industry. The Slits reformed (though not with all original members) in 2006, and released its last album Trapped Animal, in 2009.
