Kool Herc
By most accounts Herc was the first DJ to buy two copies of the same record for just a 15-second break (rhythmic instrumental segment) in the middle. By mixing back and forth between the two copies he was able to double, triple, or indefinitely extend the break. In so doing, Herc effectively deconstructed and reconstructed so-called found sound, using the turntable as a musical instrument. ... the whole chemistry of that came from Jamaica ... [Kool Herc] was born in Jamaica ...

... they had was a Sony amplifier with a Phono 1 and Phono 2 button, and that's how you switched from turntable to turntable. No fading, nothing. That was how the club like in those early seventies.
Francis Grasso
White DJ Francis Grasso invented the technique of `slip-cueing': holding the disc with his thumb whilst the turntable whirled beneath, insulated by a felt pad. He'd locate with an earphone the best spot to make the splice, then release the next side precisely on the beat...His tour de force was playing two records simultaneously for as long as two minutes at a stretch.
