Bikini Kill was an American punk rock band. Formed in Olympia, Washington in October 1990, the group consisted of Kathleen Hanna, Kathi Wilcox, Tobi Vail and Billy Karren. The group is widely considered to be the pioneer of the riot grrrl movement, and was notorious for its radical feminist lyrics and fiery performances. Their music was characteristically abrasive and hardcore punk-influenced.
While occasionally collaborating (politically and creatively) with high-profile acts such as Nirvana and Joan Jett, Bikini Kill was well-known for shunning major labels and the mainstream rock press. After two full-length albums, several EPs and two compilations, the group disbanded in 1998.
