There's no question that DJs were the face of hip hop when hip hop first came on to the scene. There are very few DJs that contributed more to the culture than Grandmaster Flash. Growing up in the Bronx (although born in Barbados), Flash was always drawn to the growing hip hop scene and after studying the technique of many DJs in the area (most notably Kool Herc), Flash began to perfect and create new styles of DJing and producing. In his book Hip Hop Matters, S. Craig Watkins documents Flash's techniques by saying, "Flash and his DJ friends believed that in every great record there is an even greater part...formally referred to as the break. Flash wanted to capture and extend the break beat because it was usually only a few seconds long. What her really wanted was to take sections of songs from vinyl and reinvent them by producing newer, longer, and funkier versions." Watkins also mentions the many terms that Flash created, including "clock theory" which described the action of re-repeating certain parts of songs by moving the record back and forth. In other words, when you're playing "DJ Hero," Grandmaster Flash was the first to do that (just for perspective lol).
