For a sklightly different angle on all this:

The Burka Band

"An all singing burka clad girl group from Afghanistan could become the new Spice Girls as they make waves across Europe.
The Burka Band are a heavy metal trio who sing and rap clad in burka's (the full hijab which covers a woman's whole body including her face) and are Afghanistan's first serious pop band since the fall of the Taliban.
The mystery group from Kabul was created by a German record company who were in the country holding music workshops for locals."

And here they are in action from YouTube.
