I'm always a sucker for some revved-up, reimagined folk music, and have been checking out what I can find online by The Imagined Village, who do some great versions of English folk music. (It's basically Eliza and Martin Carthy, plus assorted members of Afro-Celt Soundsystem, plus Sheila Chandra, plus Billy Bragg, plus even more folks with whom I'm less familiar.)
For example:
