Twenty-one years on from his death, Kurt Cobain remains an icon, but his appeal extends far beyond the average star-who-died-too-young. There are those who worship at the altar of classic grunge, those who are eternally enamoured with the hazy mythology of the 27 Club, those who revere his unique brand of exhilarating, sweat-stained performance. But a key demographic of Nirvana worshippers are the feminists, who responded to the band’s singular attitude to women and gender boundaries.

Against a backdrop of aggressive male artists – such as Guns’n’Roses and Rage Against the Machine – Nirvana set forth a pure, if at times clumsy, standpoint on equality. Their alternative rock, instead of being a thrusting assertion of their dominant sex symbol status, in fact exemplified a new, alternative breed of rock’n’roll, one that was unafraid of blurring the previously intransigent barriers between masculine and feminine strength. From lyrics informed by the Riot Grrrl subculture, the band making out with each other on Saturday Night Live, to this glorious cross-dressing spread from Mademoiselle magazine shot by Stephane Sednaoui, Nirvana were brave enough to comment on the insidious forces in society. "I'm definitely a feminist," Cobain said. "I'm fucking disgusted by the way women are still treated. It's 1993 and some people think we're in the 1950s...Everything is dominated by males and I'm fucking sick of it." And they didn't just speak their views – they literally wore their feminist hearts on their Dries van Noten sleeves.
