Who is Kathleen Hanna?

Oh,  Kathleen Hanna of Bikini Girl
I heard the buzz of the Riot Girl movement
although it was on my radar
I did not follow or monitor its actions
\
there is a movie about Kathleen Hanna

a film at West End Cinema starting Dec. 13 called THE PUNK SINGER: A Film About Kathleen Hanna
