On the contrary, I always hated Bikini Kill. But I hate that poser Kathleen Hanna, so maybe that's why. Live Through This was a record that meant a hell of a lot to me when I was younger, but everything else Hole did fell short (Beautiful Son a notable exception). L7 were fun but nothing special. Sleater-Kinney are one of the most overrated bands ever.
Sonic Youth and Courtney had a falling out in the mid-90's. Up until then they liked one other. I think it might have been over Courtney punching Hanna's lights out at that Lollapalooza.
