In the Eighties such originators as DJ Kool Herc and Grandmaster Flash began to extend the breaks (the bit with the best drumbeat) in order to keep the crowd dancing. Since then, turntablism has become an art form in itself, with DJs such as Q Bert, Craze and the Scratch Perverts, who all play at Fabric tonight, moving their records around to create new drumbeats, different basslines and wild synth stabs, through such scratching techniques as flares, crabs and orbits.
