I thought I would add my two cents. These are some of my favorites:
Concrete Blonde - Bloodletting
: I love this one if I'm feeling all gothy and nostalgic.
Poe - Haunted
: This is one of my favorite albums ever. Few people know about it, but everyone should. Every song on this album is awesome.
This album has a relentless techno beat, with a cool pop/rock melody on top.
I love Lita Ford and Janet Jackson too, of course. They remind me of being 10 and wanting to grow up to be them some day. haha I'm still working on the growing up part.
I also love those old country story songs by tough redneck chicks! You know, songs about murder, birth control, drinking, prostitution and love? hahaha Women like Loretta Lynn, Emmylou Harris, Dolly Parton, June Carter Cash, Jessi Colter and Bobbie Gentry were singing about that stuff when it wasn't OK to TALK about it! If you're not familiar you might want to check some of it out. It's more "Americana" than "Country". Think Johnny Cash rather than Shania Twain.
Makes me feel like a badass after a little bit of singing along.
BUT I would really recommend supporting your local artists. Most towns are going to have girl bands nowadays. Go and see them! Buy a CD! Let them know they rock as hard as the boys!
