Pakistani singer Nusrat Fateh Ali Khan's unknown recordings discovered

Four previously unknown recordings of Nusrat Fateh Ali Khan, the Pakistani singer known as the ‘King of the Kings of Qawwali’ who died in 1997, have been rediscovered on a warehouse shelf in England. They’re released on a new album called “Chain of Light.”
Michael Brook — the Canadian guitarist and composer who recorded the newly released tracks with Kahn back in 1990 — and Hussein Rashid, a scholar of Muslim and U.S. culture, join us.
