DJ and hip-hop pioneer Grandmaster Flash recently gave a lecture at New York’s Hot 97 on the development of hip-hop DJing. The presentation came just one week after the debut of The Get Down, a new Netflix series that explores the rise of hip-hop in the late ’70s.
The hour-long lecture focused on Flash’s technical contributions to hip-hop DJing, including the “peek-a-boo” system, which combined a microphone mixer, preamps, and a studio mixer. As Scratch DJ Academy’s book On the Record states: “this new setup enabled [Grandmaster Flash] to preview the combined sound of two records through headphones before it went through the speakers.”
Flash also explained and demonstrated his “quick mix theory,” which was made possible by the peek-a-boo system. Quick mixing enabled Flash to extend the drum break of a song indefinitely so that crowd could keep dancing to it. The technique was not only a major advancement in hip-hop DJing but led to the development of rap music.
While the innovations that Flash discussed were introduced over 30 years ago, they are still considered standard DJing techniques today.
