I LOVE female vocals! My favorite vocalists would have to be: Tairrie B, Kathleen Hanna, Jessicka Fodera, Courtney Love, Tori Amos, PJ Harvey, Katie Jane Garside, Karyn Crisis, and Donita Sparks.
I love Pink, she has that husky, original voice. She sang a duest with Steve Tyler, 'Misery' their voices were perfectly suited to each other. Her music may not be that different to other pop/rock artists but her vocals stand out.
