Scratch is a 2001 documentary film, directed and edited by Doug Pray. The film explores the world of the hip-hop DJ from the birth of hip-hop when pioneering DJs began extending breaks on records, to the invention of scratching and beat juggling, to the more recent explosion of turntablism. Throughout the documentary, many artists explain how they were introduced to hip-hop while providing stories of their personal experiences.

A disc jockey, more commonly abbreviated as DJ, is a person who plays recorded music for an audience. Types of DJs include radio DJs, club DJs, mobile DJs, and turntablists. Originally, the "disc" in "disc jockey" referred to shellac and later vinyl records, but nowadays DJ is used as an all-encompassing term to also describe persons who mix music from other recording media such as cassettes, CDs or digital audio files on a CDJ, controller, or even a laptop. DJs may adopt the title "DJ" in front of their real names, adopted pseudonyms, or stage names.
