She has been very influential on and a great inspiration for many female artist of "today". Not meaning that she doesn't belong to that era herself, just making clear how influential she has been on other artists, such as Kate Nash, and Florence Welch, etc...
One of my favorites-Has a great voice and character, which are a very good mixture in her case.
Varied styles-CD's are very different form one another.
If you like, romantic alternative female singing, this is her.
