beccatoria | Female Singers

Hey guys
First off I'm really, really sorry I've been so crap about posting here lately and stuff. It's been a bit of a grind-you-down kind of couple of weeks. But I still love you all!

In other news, HALP ME.

For reasons that are far to long and boring to be of interest to many of you, I find that I need some suggestions for female singers, or bands with female lead singers, that I might like. My music taste tends to be somewhere in the vicinity of indie rock with various odd jaunts toward both singer-songwriter and rap artist. I like complicated lyrics. I like when not all the songs are about being in love. Or if they are, the lyrics are complicated and interesting. I like drumming. I like "strong" voices rather than "pretty" voices.

Here are some female artists I already like:

Florence and the Machine
Joan Baez
Tracy Chapman
Pat Benatar (shut up!)
Jefferson Airplane
Regina Spektor
Tori Amos (during her early years)

Any recs welcome!

Thanks guys!
