The early-’90s riot grrrl movement is best summarised by Bikini Kill’s immortal four words: “Girls to the front!” A strident reaction to Reagan-era social conservatism and the male-dominated underground punk scene, the genre centred women’s voices and bodily autonomy. Both onstage and off, musicians made the personal political, tackling issues such as abortion rights, sexual assault and toxic social hierarchies with no-holds-barred clarity. Appropriately, riot grrrl’s ambassadors also went for confrontational sonics. Bratmobile favoured needling punk with nimble post-punk rhythms, pro-choice pioneers L7 skewed toward bruising hard rock and Emily’s Sassy Lime reveled in experimental noise rock. Even though riot grrrl lost momentum by the end of the ’90s, its musicians kept the genre’s feminist tenets alive. Heavens to Betsy vocal rabble-rouser Corin Tucker found greater success co-fronting the slashing punk trio Sleater-Kinney, while Kathleen Hanna moved from Bikini Kill’s whiplash hardcore to Le Tigre’s inflammatory electro-punk dance jams.
