Nusrat Fateh Ali Khan (Punjabi: نصرت فتح علی خان (Shahmukhī)) (October 13, 1948 – August 16, 1997), a world-renowned Pakistani musician, was primarily a singer of Qawwali, the devotional music of the Sufis (a mystical tradition within Islam). Considered one of the greatest singers ever recorded, he possessed a six-octave vocal range^{[citation needed]} and could perform at a high level of intensity for several hours. Extending the 600-year old Qawwali tradition of his family, Khan is widely credited with introducing Sufi music to international audiences. He was popularly known as "Shahenshah-e-Qawwali", meaning "The King of Kings of Qawwali".

Born in Faisalabad, Pakistan, Khan had his first public performance at age of 16, at his father's chelum. He officially became the head of the family qawwali party in 1971, and was signed by Oriental Star Agencies (OSA), Birmingham, U.K., in the early 1980s. In subsequent years, Khan released movie scores and albums for various labels in Pakistan, Europe, Japan and the U.S. He engaged in collaborations and experiments with Western artists, becoming a well-known world music artist in the process. He toured extensively, performing in over 40 countries.
