For my money, Andrew Cronshaw does some very good experimental folk music. He is mostly known for playing the electric zither but is also accomplished on other instruments. The use of tin whistle, lap steel, and clarinet on "Wasps in the Woodpile" on his "Till the Beasts Return" album is great. "Language of Snakes" is also good. Topic has a great sampler of his stuff. He's just released a new one, but I don't recall the title. His arrangement of "The Hawthorne Tree of Cawdor" brings tears to the eyes.
