Mehr & Sher Ali
Mehr Ali and his brother Sher Ali belong, like Nusrat Fateh Ali Khan, to the Qawwali school known as Panjabi ang. One of the surprising features of their approach is the simultaneous use of several languages (one verse might be in Farsi, another in Arabic, part of another in Punjabi and the last in Urdu) for obvious purposes of communication, arising no doubt from the particular history and geography of the Punjab.
