Sufi rock is a subgenre of rock music that combines rock with classical sufi music traditions. It emerged in the early 1990s and became widely popular in the late 1990s in Pakistan and India. The term "sufi rock" was coined in 1993 by writer Nadeem F. Paracha to define the Pakistani band Junoon, who pioneered the process of fusing conventional rock music with sufi music and imagery. Rabbi Shergill's Bullah Ki Jaana was one of the best examples of Sufi music admired in both India and Pakistan.
