DJ Kool Herc extended the drum break by alternating the same record across two turntables

Beginning in 1973, DJ Kool Herc pioneered the technique that founded breakbeat culture: he played the same record on two turntables and looped the drum break by alternating between them, so the break — the most energetic, percussive section of a funk record — could be extended indefinitely for dancers. Grandmaster Flash later refined this into his ‘quick-mix theory’, marking the break’s start and end on the record with a crayon so he could replay it precisely without touching the tone arm. The technique was popular in clubs because the extended break gave breakers (breakdancers) more room to perform, and it was copied and improved by Afrika Bambaataa and Grand Wizard Theodore. This is the manual, turntable-era ancestor of today’s beatmatching and loop-based production.

Assessment

Describe Grandmaster Flash’s ‘quick-mix theory’ in your own words. What problem did it solve over Kool Herc’s earlier two-turntable technique, and how does it relate to modern beatmatching?
