Not really sure how to classify this one, so I won't. If you dig Colon Maloy (lead singer of the Decemberists) at all, this is sort of in that vein. In fact she opens for him on a regular basis and they are featured on each other's records.
You can check out her HUSH records website here, and her myspace page here. There are also some Youtube videos of her (particularly of her opening up for Colin).
