I'm looking for some new bands to add to my ipod and I was just wondering some good bands that I could add to it. I'm looking for Indie/Folk Bands I guess?

I like soloist with acoustic guitars, also i like bands with guitars and banjos. I also like a man and a women to blend together in some songs. I've only found a few bands that I like that fit this description. Here are some videos so you have some idea of what I'm talking about, but yea, music similar to this would be nice.
