Slip-cueing is a turntable-based DJ technique which consists of holding a record still while the platter rotates underneath the slipmat and releasing it at the right moment. In this way, the record accelerates to the right speed almost immediately, without waiting for the heavy platter to start up. Slip-cueing was introduced to the disco scene by Francis Grasso, but the technique had been used for many years in the radio broadcast industry.
In the days of vinyl records and turntables, slip-cueing allowed for very precise starting of the next record. This technique was often used by radio stations to match a following song to the preceding song, preserving the beat. Francis Grasso used this method to great effect in order to create a continuous flow of music for a nightclub dance floor.
