Folks that into female singer-songwriter stuff might like trying Entertainment For The Braindead. A German woman who does folk-rocky-stuff. My personal favourite album by her is the Roadkill album, where EVERYTHING you hear is either her voice, or a banjo (and a tambourine, but that doesn't count!). Damn cool stuff.
Also, ALL of her music is Creative Commons. Sweet!
If you're into folky-stuff, Omnia is really good, too. All acoustic, and it sounds AMAZING.
I've also been listening to a bit of Nurse With Wound, who are amazing, in the bizarre american avant-garde kinda way.
