Skything are a Indiana-based duo who released a tape on Friends and Relatives this year or last, which they were kind enough to send me. They make long, hypnotic, drone-y songs but it's largely percussion based, which I thought was particularly swell. Long story short, they are working on a tape for Eggy, which is very exciting. In the meantime, you should pick up that Friends and Relatives tape, and take a listen to this live recording from their tour with Justin Clifford Rhody a few months back:
