This is an excellent Tasneef and Avaz performance of a Shomaly dialect song 
by the famous Iranian singer Sousan in Dastgahe Dashty.  Although singing Avaz 
Irani seems so natural and easy to do to us, it should be noted that a "good"
performance of it is really difficult and that is why there are not many good 
singers.  The audience applause shows that they are really enjoying themselves.
