At the beginning of the disco era in the first half of the 1970s, regular disco jocks in clubs were most concerned with the blend between one record and the next - matching tempos to make a smooth transition which, at its best, could continually alter the mood on the dancefloor without breaking the flow. At its worst the technique could turn the night into one endless and inevitably boring song.
