The early disco sound was largely an urban American phenomenon with producers & labels such as SalSoul Records (Ken, Joe & Stanley Cayre), West End Records (Mel Cheren), Casablanca (Neil Bogart), Prelude (Marvin Schlachter), P&P Records (Patrick Adams & Peter Brown) to name a few.
The disco club scene was shaped by producers like Tom Moulton & John Morales who wanted to extend the enjoyment of the music & as a consequence creating the extended mix or "Remix". Producers & re-mixers would often edit existing songs by using reel-to-reel tape machines. Their remixed versions would add in percussion breaks, new sections, and new sounds.
Other influential DJs & re-mixers who helped to establish what became known as the "disco sound" included David Mancuso, Nicky Siano, Shep Pettibone, the legendary & much-sought-after Walter Gibbons & Larry Levan who were the true pioneers of dance music.
