From an interview with Sonic Youth's Kim Gordon in Ablaze!, a Leeds-published indie fanzine from 1992 that I picked up at the Wills Moody Jumble Sale:
'I think Riot Grrrl is a really good thing. But I'm also interested in the concept of Riot Guy. Eric from Sebadoh and Pavement are kind of Riot Guy.'
Shame that didn't catch on.
