OK, I just spent a ridiculous amount of time trying to figure out where I can get Joanna Newsom's two self released albums: Yarn and Glue, and Walnut Whales. I finally found somewhere I think has them and now I'm not even sure if I want to order them. For posterity, I believe Aquarius Records may have both. Here's the page that makes me think that.
