The DJ's seamless all-night flow makes recordings source material for a live composition, a radical shift from disco on

Modulations identifies the DJ’s invention of a continuous, unbroken flow of music — individual records blended into one experience that runs all night — as one of the most radical changes in music of the last thirty years, originating in disco. It reframes the DJ as an author in a distinct sense: not a performer of original material but a curator who times and transitions between pre-recorded works to build an arc no single track could achieve. It also reframes what a recording is: not a finished product but source material for real-time composition on the dance floor.

Examples

Disco DJs building hours-long journeys through selection and mixing; Frankie Knuckles at The Warehouse creating an all-night flow rather than playing discrete songs.

Assessment

What is the DJ’s compositional contribution in this frame, and how does the ‘seamless flow’ idea change what a recorded track is understood to be versus what it does?
