Followed by Nina Simone, PJ Harvey, Siouxsie Sioux, Anna Karina, Tobi Vail, Kathleen Hanna, Patti Smith, Kim Gordon....I'm sure there are many I've left out.
Oh, and to whoever mentioned Karen Carpenter: yes. Her voice is so haunting. My mum used to play The Carpenters when I was a child and for some reason I can't hear one of their songs now without a surge of sadness overcoming me, which is really strange. Her voice was amazing.
