In the early years of hip hop, the DJs were the stars, as they created new music and beats with their record players. While DJing and turntablism continue to be used in hip hop music in the 2010s, the star role has increasingly been taken by MCs since the late 1970s, due to innovative, creative MCs such as Kurtis Blow and Melle Mel of Grandmaster Flash's crew, the Furious Five, who developed strong rapping skills. However, a number of DJs have gained stardom nonetheless in recent years. Famous DJs include Grandmaster Flash, Afrika Bambaataa, Mr. Magic, DJ Jazzy Jeff, DJ Charlie Chase, DJ Disco Wiz, DJ Scratch from EPMD, DJ Premier from Gang Starr, DJ Scott La Rock from Boogie Down Productions, DJ Pete Rock of Pete Rock & CL Smooth, DJ Muggs from Cypress Hill, Jam Master Jay from Run-DMC, Eric B., DJ Screw from the Screwed Up Click and the inventor of the Chopped & Screwed style of mixing music, Funkmaster Flex, Tony Touch, DJ Clue, Mix Master Mike, Touch-Chill-Out, DJ Red Alert, and DJ Q-Bert. The underground movement of turntablism has also emerged to focus on the skills of the DJ. In the 2010s, there are turntablism competitions, where turntablists demonstrate advanced beat juggling and scratching skills.
