Just happened across this group (thank you, AsianJunkie), and was completely blown away.

Vidan is a five-membered "girl group" from Mirrorball Music that plays traditional Korean instruments, consisting of GoEun (percussion), SungAh (gayageum), HyoEun (haegum), Eunjung (vocals/pansoori) and Bicna (daegum). Their music videos are considered "Korean heritage documentary concerts", because they also function as interactive information about Korean treasures (the videos have been released in English, Korean and Russian formats). Their first album is titled "Opening New Age", and they've released videos for the title track, "Whispers of Love: Chung-Hyang's Story", "Waltz Of Moonlight" and "Standing On The Bow".

OP note: These women are *fantastic*. The vocals in "Opening New Age" made my jaw literally drop. I apologize for any errors with the members' names, as there is little to no information in English about them, and I had to run things through a translator. Also, edited to take a different photo (as my original one was not showing up) and a few grammar/coding issues.
