===DJs===
Disco-era [[disc jockey]]s (DJs) would often remix existing songs using [[reel-to-reel tape recorder|reel-to-reel tape machines]], and add in percussion breaks, new sections, and new sounds. DJs would select songs and grooves according to what the dancers wanted, transitioning from one song to another with a [[DJ mixer]] and using a [[microphone]] to introduce songs and speak to the audiences. Other equipment was added to the basic DJ setup, providing unique sound manipulations, such as [[reverb]], equalization, and echo [[effects unit]]. Using this equipment, a DJ could do effects such as cutting out all but the bassline of a song and then slowly mixing in the beginning of another song using the DJ mixer's crossfader. Notable U.S. disco DJs include [[Francis Grasso]] of The Sanctuary, [[David Mancuso]] of [[The Loft (New York City)|The Loft]], [[Frankie Knuckles]] of the Chicago [[Warehouse (nightclub)|Warehouse]], [[Larry Levan]] of the [[Paradise Garage]], [[Nicky Siano]] of [[The Gallery (disco)|The Gallery]], [[Walter Gibbons]], [[Karen Mixon Cook]], [[Jim Burgess (producer)|Jim Burgess]], [[John "Jellybean" Benitez]], Richie Kulala of [[Studio 54]], and Rick Salsalini.

Some DJs were also record producers who created and produced disco songs in the [[recording studio]]. Larry Levan, for example, was a prolific [[record producer]] as well as a DJ. Because record sales were often dependent on dance floor play by DJs in the nightclubs, DJs were also influential in the development and popularization of certain types of disco music being produced for record labels.
