Joseph,
If you can find it, I would highly recommend that you pick up the 1988 King Record release, "The Silk Road II-Chinese Music of the Hans & the Uigurs." Some very soulful string playing on that disc. Also recommended and in a similar vein: Turkestan Chinois/Xinjiang (Musiques Ouigoures), a 2-disc set released in 1990 on Ocora. I am very much into this music as well. A few years back, I picked up a Khushtar (a Uyghur violin with sympathetic strings), which I finally worked into one of my recent pieces for my next CD project.
