Kathleen Hanna (born 12 November 1968) is a musician, zine writer and one of the founders of the riot grrrl movement.
Hanna was born in Portland, Oregon and attended The Evergreen State College in Olympia, Washington in the late 1980s, where she published zines, got involved in underground music and feminist issues. Hanna and Tobi Vail did a zine called Revolution Girl Style Now and, together with Kathi Wilcox, wrote the zine Bikini Kill as a response to what they saw as sexism in the punk rock scene. The three women later formed a band of the same name. Later after relocating to D.C. in 1991, Hanna, along with Allison Wolfe and Molly Neuman from Bratmobile, published the zine riot grrrl, which helped motivate the emerging feminist movement in the punk rock scene with a call to action. The result was an exciting movement that captured national attention and was the source of quite a few zines and bands. While riot grrrl petered out within a few years, it's effect on the music scene continue to last to this day.
After Bikini Kill and riot grrrl, Hanna went on to front the fairly popular electronic feminist band Le Tigre. She moved to New York and also began to perform as a solo artist. In the summer of 2006, Hanna married Adam Horovitz of the the Beastie Boys.
