Jeffrey Scott Buckley, raised as Scott Moorhead, was an American musician. After a decade as a session guitarist in Los Angeles, Buckley amassed a following in the early 1990s by performing cover songs at venues in East Village, Manhattan, such as Sin-é, while gradually focusing more on his own material. After rebuffing interest from record labels and Herb Cohen—the manager of his father, singer Tim Buckley—he signed with Columbia, recruited a band, and recorded what would be his only studio album, Grace, in 1994.

Ustad Nusrat Fateh Ali Khan was a Pakistani singer, songwriter, and music director. He was primarily a singer of qawwali, a form of Sufi devotional music. Often called the "Shahenshah-e-Qawwali", he is considered by The New York Times to be the greatest Qawwali singer of his generation. He was described as the fourth greatest singer of all time by LA Weekly in 2016. He was known for his vocal abilities and could perform at a high level of intensity for several hours. Khan is widely credited with introducing Qawwali music to international audiences. He was also a master of Hindustani classical music.
