So here's an offering. Not as hip as Sa Dingding, true, but still fun. This comes from a collection of music put together by Aik Yew-goh, described by All Music Guide as "an Asian Alan Lomax." High praise, and high audio quality as well. His work is a fascinating glimpse into a wide variety of Chinese music that really isn't widely available in the West.
from Hugo Masters: an Anthology of Chinese Classical Music, Vol. 1 - Bowed Strings
You can still find this album and the other three volumes in the set if you look around a little. Get it and impress your friends and amaze your enemies with your knowlege of Chinese folk music!
