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. Content Elements In the first chapter, Grand Wizard Theodore explains the differences between rap and hip-hop, which are often confused. He explains that graffiti, breakdancing, DJing, MCing, and the way you talk and dress are all elements of hip-hop. Afrika Bambaataa presents a neighborhood in the Bronx which used to be called "the house of hip-hop" where violence and gangs were common. After a trip to Africa, he created what is known as the Universal Zulu Nation, a group of socially and politically aware rappers, B-boys, graffiti artists and other people involved in hip-hop culture. The importance of the DJ is shown by how he or she selects and controls the music with respect to the audience's needs. The relation and differences between DJs and MCs are explained, going through their roles in the music industry. Artists such as DJ Jazzy Jay, Grand Mixer DXT, Almighty K.G., Kevie Kev, Dot A Rock, and Steinski explain the beginning of hip-hop and its evolution since the 1970s. Concerts of breakdance and DJ performances are shown such as The Herculords, Electronic Boogaloos, Original Graffiti Rock, "Wild Style" 1982 with Busy Bee & Grand Wizard Theodore and Grand Master Flash. Rockit In the second chapter, Mix Master Mike shares his first experience with scratch through the 1984 Grammy Awards with Herbie Hancock & Grand Mixer DXT. This is the evolution of a new hip-hop transmitted from DJs to DJs. DJ QBert explains how turntables function, describing each part. He compares it to "talking". When Mix Master Mike scratched with DJ QBert, they used their scratching to communicate together. They describe it as an art and a form of intelligence. Other artists describe the popularity it had in the 1980s amongst youth at parties and battles. Many of them achieved fame through their talent in battles. Some of them made the existence of the DJ without the MC possible. This chapter features DJ Marz, DJ Eddie Def, DJ Cue, DJ Quest (Bullet Proof Space Travelors), Billy Jam,
