Download This music is called Qawwali.
It is the devotional music of the Sufi Muslims.
Qawwali is a vibrant musical tradition that stretches back more than 700 years.
It is mainly performed at Sufi shrines throughout the subcontinent including in the North West Frontier Province of Pakistan.
But in recent years music programs have been cancelled, CD stores and venues bombed by Pakistan Taliban militants who claim such events violate Islamic law.
As Mudassar Shah reports the situation has forced the Qawwali events underground.
On the day he attended one such event in Peshawar a CD shop was blown up just three hundred meters away.
