Continuing with 'classical Persian' music:

Persian & Middle Eastern Percussion (Zarbang)
Whisper (Ali Akbar Moradi, Pejman Hadadi)
Night Silence Desert (Mohammed Reza Shajarian, Kayhan Kalhor)

Next week will be more Persian music, and the week after that (or, two weeks after that), we'll be looking at music from Afghanistan.

PS The music doesn't start until around 0:40.
PPS I'm pretty sure the daf is not made of wool. Please forgive my orientalist ignorance.
